CPLOG= parameter for procedures

Use the CPLOG= parameter in procedures to specify the number of system log records between system-generated checkpoints.

If you do not code CPLOG=, the default number of log records between checkpoints is 500,000. To use a different value, you must specify a value on CPLOG= that meets both of the following requirements:

It must contain one or more numeric characters followed either by K (for thousand) or M (for million). For example, specify 1K, not 1000.
It is in the range of 1K to 16M.

K means 1024, and M means 1024*1024, for example, 100K = 102,400 and 1M = 1,048,576.
