grep.com
Author: (Norbert) Suedland, Aalen, Germany
A search programme in source texts, which needs an extension to Unicode, and by this is
a programming task for the beginning.
The possible control parameters are ascertained by a call (with argument ?) of:
grep.com ?
where the English explanation reads the following:
Turbo grep 5.0 Copyright © 1992, 1997 Borland International
Syntax: grep [-rlcnvidzuwo] search_string file[s]
Options are one or more option characters, preceeded by "-", and optionally followed
by "+" (turn option on), or "-" (turn it off). The default is "+".

A regular search expression is one or more occurences of:
One or more characters, optionally enclosed in quotes.
The following symbols are treated specially:
| ^ | |
start of a line | |
$ | |
end of a line |
| . | |
any character | |
\ | |
quote the next character |
| * | |
match zero times or more | |
+ | |
match once or more |
| [aeiou0-9] | |
match a, e, i, o, u, and 0 through 9 |
[^aeiou0-9] | |
matching anything, except for a, e, i, o, u, or 0 through 9 |
Whether in case of a translation of this programme into other languages also all option characters
are to be translated, can be discussed.
The following call finds a connection to the starting function wmain (wide_main_function) for
Unicode characters under Windows:
grep.exe -diw wmain \Borland\BC5\*.*
