Dear Jason,
We have a general file search routine in our library.
; NAME:
; file_search
;
; PURPOSE:
; This function searches a file in the current directory or in a list
of directories
; This function does return the first file which was found to match
the search
; criterion. Use the wild cards '*' or /LIST keyword to return a full
list.
;
; CATEGORY:

;
; INPUTS:

;
; KEYWORD PARAMETERS:
; DIRECTORIES: string (array) containing a list of directories to
be searched
; NO_CURRENT: if set the current directory is not searched !
; ENV_VAR: name of a environment variable containing a path
; USE_PATH: if this keyword is set the path of IDL is used for
search
; SEARCH_TREE: if this keyword is set the search is expanded to all
subdirs of the
; given directories, equivalent to a preceeding '+' in
the directory name
; FILE_COUNT: if set to named variable the number of file hits is
