Arguments

 

number-of-descriptors

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Number of adjacent descriptors freed by LIB$SFREEN_DD. The
   number-of-descriptors argument contains the address of an
   unsigned longword that is this number. The deallocated area is
   returned to free storage.
 

first-descriptor-array

   OpenVMS usage:descriptor_array
   type:         quadword (unsigned)
   access:       modify
   mechanism:    by reference, array reference

   First descriptor of an array of descriptors. The first-
   descriptor-array argument contains the address of this first
   descriptor. The descriptors are assumed to be dynamic, and their
   class fields are not checked.

   The descriptor array must contain all 32-bit descriptors or all
   64-bit descriptors. They cannot be mixed.
