Since the search gave me either too much or too little, but invariably got me into the wrong direction, here's the problem, hoping the solution will be something simple I've overlooked from the start:

We have a little launcher app which just checks for the existence of an executable (there may be 3 or more executables in different directories), and displays a command button for each of the exes found. Now I need to replace the "for each of the exes found" with "for each of the exes the current user has the rights to execute". So, instead of "if file(lcExeName)" it would be "if [insert function name here, please](lcExeName)".

Is there any such beast? Does need to work on Linux, CP/M, VAX or AS400, just W2K.

TIA, you'll save my day.
