Purges the memory-resident form listvoid sm_rmformlist(void);
sm_rmformlisterases the memory-resident form list established by sm_formlist, and releases the memory used to hold it. It does not release any of the memory-resident JPL modules or screens. Calling this function prevents sm_r_window, sm_jplcall, and related functions from finding memory-resident objects.
/* Hide all the memory-resident screens, perhaps
* because the disk versions have been modified. */
