SQR exists function

In an SQR where if we want to check if a file exists on the server, one can use the function

#filexist = exists($Exact_FileName);

If it exists, then #filexist would be 0. But if I don't have the exact file name because the file on the server may have suffix such as date time, then is there a way to find such files. For example I am looking for files beginning with "ABC" but the files on the server could be "ABC_123". Is there a SQR function for that?

Thank you.
