BLINKER OVERLAY FIXED         Specify fixed overlay allocation method
------------------------------------------------------------------------------

 Purpose  : Specify fixed overlay allocation method

 Syntax   : BLINKER OVERLAY FIXED

 Default  : Enabled (Optional for CA-Clipper Summer '87)

 This command is used to instruct Blinker to allocate a fixed size block of
 memory from DOS for overlays at application start up. Once the block has
 been allocated from DOS, the Blinker overlay manager will not allocate any
 further memory for overlays, resulting in an application with a predictable
 overlay overhead. This method allows parental overlays (procedures or
 functions that called the current procedure) to be swapped out as required,
 in order to make room to execute new procedures.

 This method is the only overlay pool allocation method for all compilers
 except CA-Clipper Summer '87, where it is optional.

 Please see the previous section, BLINKER OVERLAY DYNAMIC, for a comparison
 of the FIXED and DYNAMIC methods.
