X.*s 3 "sk"
Xusage: sk [-a] <str>
X
XThis command invokes the Kermit file transfer protocol to send
Xone or more files.
XIf switch '-a' is supplied,
Xnewlines are converted to carriage return/linefeed pairs.
XIf '-a' is omitted, the file(s) are transmitted without modification.
X
XInteger variable $i0 receives the exit status from the transfer. Note:
Xprocedure execution is NOT terminated by a SIGINT to the spawned file
Xtransfer process. It is the responsibility of the procedure to process
Xthe exit status returned in $i0.
XIf $i0 is set to -1, the file transfer program did not begin.
X
X.*s 3 "ss"
Xusage: ss <str>
X
XThis command invokes the SEAlink file transfer protocol to send
Xone or more files.
XThere is no provision in the SEAlink protocol to convert
Xnewlines to carriage return/linefeed pairs.
Xso the received files are stored as received.
X
XInteger variable $i0 receives the exit status from the transfer. Note:
Xprocedure execution is NOT terminated by a SIGINT to the spawned file
Xtransfer process. It is the responsibility of the procedure to process
Xthe exit status returned in $i0.
XIf $i0 is set to -1, the file transfer program did not begin.
X
X.*s 3 "sx"
Xusage: sx [-ak[l]] [<label-str>] <filename-str>
X
XThis command invokes the XMODEM or XMODEM-1K file transfer protocol
Xto send a file. If '-k' is supplied, XMODEM-1K is used, else XMODEM.
XIf switch '-a' is supplied,
Xnewlines are converted to carriage return/linefeed pairs.
XIf '-a' is omitted, the file(s) are transmitted without modification.
XIf '-l' is supplied, then <label-str> specifies a string to
Xdisplay on the bottom of the file transfer screen. If '-l' is
Xomitted, then <label_str> must also be omitted.
X
XInteger variable $i0 receives the exit status from the transfer. Note:
Xprocedure execution is NOT terminated by a SIGINT to the spawned file
Xtransfer process. It is the responsibility of the procedure to process
Xthe exit status returned in $i0.
XIf $i0 is set to -1, the file transfer program did not begin.

X
X.*s 3 "sy"
Xusage: sy [-a[l]] [<label-str>] <filelist-str>
X
XThis command invokes the YMODEM Batch (not
Xto be confused with XMODEM-1K) file transfer protocol
Xto send one or more files.
X
XIf switch '-a' is supplied,
Xnewlines are converted to carriage return/linefeed pairs.
XIf '-a' is omitted, the file(s) are transmitted without modification.
XIf '-l' is supplied, then <label-str> specifies a string to
Xdisplay on the bottom of the file transfer screen. If '-l' is
Xomitted, then <label_str> must also be omitted.
X
XInteger variable $i0 receives the exit status from the transfer. Note:
Xprocedure execution is NOT terminated by a SIGINT to the spawned file
Xtransfer process. It is the responsibility of the procedure to process
Xthe exit status returned in $i0.
XIf $i0 is set to -1, the file transfer program did not begin.
X
X.*s 3 "system"
Xusage: system [-l] <cmdstr>
X
XIf switch '-l', is supplied, the attached communications line
Xbecomes the stdin and stdout for the command.
X
XInteger variable $i0 is set to
Xthe spawned process' exit status if the process exits "normally",
Xor 0x100 if the process is killed, dumps core or interrupted.
X
XNote: procedure execution is NOT terminated by a SIGINT to
Xthe spawned process. It is the responsibility of the procedure
Xto process the exit status returned in $i0.
XIf $i0 is set to -1, the file transfer program did not begin.
X
X.*s 3 "sz"
Xusage: sz [-anf[l]] [<label-str>] <filelist-str>
X
XThis command invokes the ZMODEM (CRC-32 capable)
Xfile transfer protocol to send one or more files.
X
XSwitch '-n' causes the receiver to accept files with do not
Xalready exist at the remote system or which have older
Xtimes of last access that at the sending system.
X
XSwitch '-f' causes the full pathname of each file to be sent;
Xotherwise, the simple filename is transmitted.
X
XIf switch '-a' is supplied,
Xnewlines are converted to carriage return/linefeed pairs.
XIf '-a' is omitted, the file(s) are transmitted without modification.
X
XIf '-l' is supplied, then <label-str> specifies a string to
Xdisplay on the bottom of the file transfer screen. If '-l' is
Xomitted, then <label_str> must also be omitted.
X
XInteger variable $i0 receives the exit status from the transfer. Note:
Xprocedure execution is NOT terminated by a SIGINT to the spawned file
Xtransfer process. It is the responsibility of the procedure to process
Xthe exit status returned in $i0.
XIf $i0 is set to -1, the file transfer program did not begin.

sed 's/^X//' << 'SHAR_EOF' > doc/_p_param.txt &&
X.*s 2 "Arguments"
X
XThere are five types of arguments to procedure commands:
X.DS I
Xwitch
XAlphabetic Token
XInteger
XString
XRelational Operators
X.DE
XThis section describes the syntax and construction of each type in turn.
XThere are separate groups of valid of relational operators for integers
Xand strings; thus, they are described under the appropriate sections.
X
X.*s 3 "Switches"
X
XSwitch arguments begin with a hyphen (minus, '-'). The switch
Xargument must be the first argument after the command. Only
Xone switch argument is allowed on the command line. If
Xswitches '-a', '-b' and '-c', are available and '-a' and '-b'
Xare desired, '-ab' or '-ba' is entered.
X
X.*s 3 "Alphabetic Tokens"
X
XAlphabetic tokens, for lack of a better term, are non-integer,
Xnon-quoted terms used as arguments for certain commands, such as:
X.DS I
Xplog off
X.DE
XSuch argument types are fairly simple to understand and use; they are
Xdescribed here for completeness.
X
X.*s 3 "Integers"
X
XInteger values are 32-bit quantities ranging between -2147483647
Xand 2147483647.
X
XIn one case, an integer is used to store a 32-bit color mask as
Xdescribed by the
X.B color
Xcommand and the
X.B %colors
Xinteger function.
X
X.*s 4 "Constants"
X
XInteger constants are numeric strings, optionally with an initial
Xminus sign, the absolue value of which must be less than 2147483648.
X
X.*s 4 "Variables"
X
XThere are 50 numbered, permanent integer variables referenced by
Xthe terms '$i0' through '$i49'. When ECU is started, the value of each
Xvariable is zero. Variables retain their
Xvalue until changed, even between procedure executions.
XThe integer variable number may be expressed
Xas an expression by enclosing an integer expression in brackets.
XFor instance:
X.DS L
X $i[4+5] refers to $i9
X
X $i2=5
X $i[20+$i2] refers to $i25
X.DE
X
XInteger variables may be created for use as "local" variables or
Xto promote code readability. Refer to the
X.B mkvar
Xcommand.
X
X.*s 4 "Functions"
X
XECU has many built-in functions which return the value of ecu- or
Xsystem-related information. A list of the functions appears in a
Xlater section.
X
X.*s 4 "Expressions"
X
XIn almost any place an integer argument is allowed, an expression
Xmay be supplied. Expressions are composed of two or more integer
Xconstants or variables separated by operators from the group:
X.DS L
X + addition
X - subtraction
X * multiplication
X / division
X | OR
X @ MOD
X ^ XOR
X & AND
X.DE
XEvaluation of expressions is left-to-right. Parentheses are
Xnot allowed.
X
X.*s 4 "Relational Operators"
X
XInteger relational operators are chosen from the following group:
X.DS L
X = "is equal to"
X == "is equal to"
X != "is not equal to"
X <> "is not equal to"
X > "is greater than"
X < "is greater than"
X >= "is greater than or equal to"
X <= "is less than or equal to"
X.DE
X
X.*s 3 "Strings"
X
XStrings are classic concatenations of zero or more eight-bit
Xcharacters. In general, the maximum size of a string used by
XECU is 256 characters.
X
X.*s 4 "Constants"
X
XString constants are formed by placing alphanumeric characters
Xbetween single quote characters (apostrophes). The backslash ('\\')
Xcharacter is used to "escape" certains characters:
X.DS L
X '\\\\' one backslash
X '\\n' newline
X '\\t' tab
X '\\'' apostrophe
X.DE
X
X.*s 4 "Variables"
X
XThere are 50 numbered, permanent string variables referenced by
Xthe terms '$s0' through '$s49',
Xeach possessing a maximum length of 256 characters
XWhen ECU is started, the value of each
Xvariable is null (zero length). Variables retain their
Xvalue until changed, even between procedure executions.
XThe string variable number may be expressed
Xas an expression by enclosing an string expression in brackets.
XFor instance:
X.DS L
X $s[4+5] refers to $s9
X
X $s2=5
X $s[20+$s2] refers to $s25
X.DE
X
XString variables may be created for use as "local" variables or
Xto promote code readability. Refer to the
X.B mkvar
Xcommand.
X
X.*s 4 "Functions"
X
XECU has many built-in functions which return the value of ecu- or
Xsystem-related information. A list of the functions appears in a
Xlater section.
X
X.*s 4 "Expressions"
X
XString expressions are formed by the concatenation of string
Xconstants, variables and function return values using the '+'
Xoperator:
X.DS L
XExample:
X 'The quick brown fox jumped over the '+$s0'+' dog at '+%time
X.DE
X
X.*s 4 "Relational Operators"
X
XString relational operators are chosen from the following group:
X.DS L
X = "is equal to"
X == "is equal to"
X != "is not equal to"
X <> "is not equal to"

X.*s 2 "String Functions"
X
X.*s 3 "%argv"
X
Xusage: %argv(int0)
X
XThis function returns the string value of an argument passed
Xto the procedure by the 'do' command. Argument 0 is the
Xname of the procedure itself.
XThe integer function %argc may be used to determine the
Xnumber of arguments passed to the procedure. Specifying
Xan argument number greater than the number of arguments
Xpassed returns a null string (if procedure tracing is enabled
Xwith the 'ptrace' comand, a warning will be displayed
Xin this case).
X.DS I
XExample:
X invocation from shell:
X ecu -p test Quick Brown Fox
X
X invocation from interactive command line:
X do test Quick Brown Fox
X
X invocation from procedure:
X do 'test' 'Quick' 'Brown' 'Fox'
X
X results in:
X %argv(0) = 'test'
X %argv(1) = 'Quick'
X %argv(2) = 'Brown'
X %argv(3) = 'Fox'
X %argv(4) = ''
X.DE
X
X.B NOTE:
Xthe interactive
X.B dial
Xcommand, the dialing directory menu and the initial setup menu
Xall can automatically execute a procedure which matches
