USR FSFILEEXISTS(fsSpec) Revised February, 2002 (Release 6) Description - Your program may determine whether or not a file exists using this function. A non-zero value is returned when the file is present. You need to pass a file spec record which can be created using FN FBmakeFSSpec or by using a file spec version of the FILES$ function. To determine if a file named "My File" is present in the application folder your would use the following code. INCLUDE "Util_Files.incl" DIM fs AS FSSpec FN FBmakeFSSpec(SYSTEM(_aplVol),0,"My File",fs) LONG IF USR FSFILEEXISTS(fs) PRINT "File exists!" END IF Note: You will not be able to use this function unless you include the proper header file as follows: INCLUDE "Util_Files.incl" See Also USR FILEEXISTS; Appendix H: File Spec Records; FILES$
