Validman Improvements

Validman validations now generate code that responds to "?" in field or Cursor in field and F4 pressed (just like LISTPGMs) and pass the "$" field to Validman and '?' in the @@@RTN parameter so that it locates to the code in the "$" field. Validman validations now respond to cursor in the field and F4 is pressed, so Validman validated fields act exactly like a field validated with an e'X'istence check and with a LISTPGM enquiry program to support selection. The DDS key words permitting the pressing of F4 are automatically generated for Validman validations.

This is also true of the LISTPGM / F4PGM verb which used to require a dummy "04" pgm logic line to tell the generator that F4 was an allowed function key (You may still wish to enter the dummy line in the pgm logic section so that the F key description, which appears on line 23 of the display DDS, can be created without formatting the Panel trailer format.)
