[ENHANCED] VFP 9.0 FIX - THE DEFAULT VALUE FOR THE PROGCACHE TERM IN THE CONFIGURATION FILE
January 2024
-----------------------------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9, the default value is 144 pages (9 MB) for the PROGCACHE term in the configuration file,
now the default value is 1024 pages (64 MB) for the PROGCACHE term in the configuration file.
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
