This version of the PopUp-Module does not run in low or medium resolution.
In the reference manual of Master V5.70 you'll get a complete description of
the Master-Module-eXtension interface. On the original disk of V5.70 you'll
also get a sample module in source-form (written in C).
The online-help for the MENU-command (implemented by this module) in MASTER.HLP
is unabridged.
