4GL function needed
Is there any 4GL function that checks if a string is an integer?

I'm using 4GL 7.20.ud6: Just set the integer variable equal to the string variable. If the string is numeric, then the integer variable will be set to the value of the string. If the string is alpha, then the integer variable will be null. WHENEVER ERROR STOP will show a status of 0 immediately after the conversions; the only difference being that the integer variable will be null. If your applications are set to WHENEVER ANY ERROR CONTINUE, then status will be set to -1213 for the character to numeric conversion.
