 BLINKER OVERLAY FIXED
------------------------------------------------------------------------------
 Purpose:
 Specify fixed overlay allocation method.

 Syntax:
 BLINKER OVERLAY FIXED

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

 Description:
 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.
