It seems to me that if your database contains simply lines with certain
characters in each column, and you want to search for lines matching a
specified pattern of characters, the simplest thing to use is grep.
You gave an example of finding "only the records with (a) in col1, (nop) in
col19-21, (v) in col29 and (y) in col34." How about:
grep "^a................. .......v....y" database-filename
Read the man page for grep if you don't understand the periods in the regular
expression above.
