Use BUFSIZE to allocate an amount of main storage to the buffer for each compiler work data set. Usually, a large buffer size improves the performance of the compiler.
Default is: 4096
Abbreviations are: BUF
nnnnn specifies a decimal number that must be at least 256.
nnnK specifies a decimal number in 1-KB increments, where 1 KB = 1024 bytes.
If you use both BUFSIZE and SIZE, the amount allocated to buffers is included in the amount of main storage available for compilation via the SIZE option.
BUFSIZE cannot exceed the track capacity for the device used, nor can it exceed the maximum allowed by data management services.
