If you do not use SET CLIPPER to alter the memory allocation, the
Clipper program automatically allocates the available memory in the
. The executable load module is loaded into memory above DOS.
. 24K bytes are reserved for a free memory pool.
. Of the remaining available memory, 20 percent is allocated for
memory variables (44K maximum).
. Of the memory remaining, 33 percent is allocated for RUN commands
and index buffers (16K minimum).
. The remaining available memory is added to the previously reserved
24K bytes, and allocated to the "free memory pool" to be used for
program processing. Specific uses of "free memory pool" include
storage of character variables, arrays, and transient copies of
database records from open database files.
Accordingly, the absolute minimum memory required above DOS to run
your application is the load module size, 24K for the free pool, 16K
for index buffers, plus the allocation for memory variables.
If Expanded Memory is present, the Clipper program automatically
makes use of it allocating up to one megabyte, if available, for
index buffers. The allocation described in step 4 above will only be
used for RUN commands. If Expanded Memory is present, the Clipper
program requires a minimum of 16K bytes of the Expanded Memory.
