That is: parse a file SOME_FILE.PRO and find if it contains any function
of your own library.

1- You need to load into memory (array) a list of your functions name.

2- Read each file line.

3- I think it will better with a STRMACTH or STREGEX.
This code can help you (extract from the old post
http://groups-beta.google.com/group/comp.lang.idl-pvwave/bro wse_thread/thread/bd3fc18ab72631ea/33089f602feb945c?hl=en#33 089f602feb945c):
Parse an entory file 'file' and found all functions or procedures that
starts with 'findstring'.
;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

4- I dont understand this part. Save the function that coincides with
your function names and then find recursively into functions with
different name??
