I believe comp.lang.idl is not about the Interactive Data Language, but
about some Interface Description Language.

This might help:

Still, file_which should also work if the source file is in the IDL
path. And I think you should always have your source files in the path.

I almost nothing have used IDLDE (I use Emacs+IDLwave).
I testes your previous command in the IDL command line interpreter all
works fine. Perhaps you need to modify your IDLDE configuration path or
simething like this.

That is, yoru file.pro cotains procedured "fred" and "tom" ??
I think there is no function that does this for you, you need to open
and parse the file looking for a "PROCEDURE fred" string.
The next procedure opens a file and search for all procedure/funtions
that starts with the specified "findstring". If you put
findstring='fred' then also match names like 'frederic'.
;PRO parse, file, findstring
;; Open the file test.lis:
OPENR, 1, file
;; Define a string variable:
line = ''
;; Loop until EOF is found:
found = 0
line_number = 0
WHILE (~ EOF(1)) AND (NOT found) DO BEGIN
;; Read a line of text:
READF, 1, line
;; Check if match your procedure/function name
match = STREGEX(STRUPCASE(line), '(PROCEDURE|FUNCTION) ' + $
''+STRUPCASE(findstring), $
/BOOLEAN)
IF match THEN print, line_number, '-', line
line_number++
ENDWHILE
;; Close the file:
CLOSE, 1
END

could be done in several ways
* if it is compiled, help,/source,out=out
* look for "current directory" or "get_profile_path" in the google forum or
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/get_profile_path_dbase.pro.html
* file_which if the routine is in !PATH

you should think on using a startup script which organises the !path for
you. A startup file is used in idlde and idl the same way. just only an
environement variable IDL_STARTUP must be set to this file.

Then you want to separate between path file and extension.
you should have a look at:
