h_pack()                Pack Clipper's free memory pool.
----------------------------------------------------------------------------------------

 Syntax:

 h_pack()

 Description:

 This option packs Clipper's free memory pool for more efficient variable
 storage.

 h_pack() works by joining neighboring free blocks because Clipper will
 not treat two neighboring 512 byte blocks as a single 1024 byte block
 (1K).  Instead, Clipper will get a fresh 1K block from the heap. 
 h_pack() forces the two 512 byte blocks to be viewed as a single 1K
 block.
