Help with AWK

[jdm]

I have been attempting to teach myself AWK on a Sun 386i running SunOS
4.0.1.  After entering numerous examples of AWK code from the book "The
AWK Programming Language" by Aho, Kernighan, and Weinberger, I find that
none of them run!  I get error messages complaining about expressions and
syntax and none of the messages give me an indication of a definitive
problem.

I wrote an AWK program to replace a specific character in a file with
another:

	/;/ { sub(/;/, "X", $0) }  # replace all ; with X

and AWK choked on the sub() function.  Likewise AWK dosen't seem to
recognise "getline", "gsub", "index", "substr", etc.  Does SunOS come with
an older version of AWK that does not implement these functions?  If not,
what is going wrong?
