Description:

This form of MME GEMORE requests additional memory, in blocks of 1K. If the memory can be obtained successfully, it is added at the high end of the program.

A single call to MME GEMORE can obtain up to 64K of additional memory. However, large requests may cause delays, as the program is suspended until the total space is available.

The memory request may be denied for the following reasons.

-- more than 64K requested
-- not enough mass storage to hold swap file
-- outstanding abort request on program
