Here is a simple technique for removing editing characters from a date field. Use the CHECK op code to find the delimiters, and use the EVAL op code and %SUBST built-in function to take them out.
Figures 7 and 8 contain the prototype and the subprocedure RMVDTSEP (Remove Date Separators) for this technique.
This method can be used with dates in formats MM/DD/YY, YY/MM/DD, CCYY/MM/DD, or MM/DD/CCYY, and it works with any nonblank separator character.
