exists or similar command to work like grep on file system files

[James Flanagan]

Server: 	FreeBSD 9.2
Filepro:	5.7.0.4

I am looking a way to have filepro verify whether a file exists using only a partial file name (like grep).  This will be used with photographs from all sorts of cameras so instead of trying to account for every possible camera filename structure, i would like to be able to supply filepro with 3-4 numbers and a directory and have filepro determine if a file with that number exists in a file name.  that will be accurate enough for what i need the code to do.  

below is a simple file list, and beneath that is how i would imagine i would use the exists command to accomplish what i am trying to do (however it does not appear to work with asterisk variables).  Is there either different syntax to use with the exists command, or possibly a different command that will do this?  I could use a system command that could LS the directory and then grep the result to a file, and then use exists on that output file, but i am looking to see if there is a more elegant solution self contained within filepro itself.   Thank you very much in advance.

::aa="0998":
:exists("/tmp/a/*"{aa{"*") eq "1":msgbox aa<"exists":
