                                 L_EMMFREE()


Syntax:        L_EMMFREE()


Purpose:       To determine the number of expanded memory pages which
               are available for use.


Arguments:     None.


Returns:       An integer value.
               This value is the total number of EMM pages available
               for use in the system.

               One page is equal to 16K.

               Multiply this returned value by 16 to determine the
               total number of kilobytes.


Usage:         Use this function ONLY after calling L_ISEMM() to
               determine if the EMM driver is present and L_EMMSTAT()
               to determine if the EMM hardware and software is
               operational.


Examples:      * find available expanded memory
               avail = L_EMMFREE() * 16


Language:      Assembler
