CCPPOL

The CCPPOL macro is used to specify shutdown and restart levels for polling each non-SNA line type based on the size of the input list. Polling will stop when the size of the input list exceeds the shutdown level for that line type. Polling will restart when the size of the input list is less than the restart level. For SLC, these values are used to control the message rate. If the shutdown level is exceeded, a STOP ALL is sent and no data is sent across the link until the input list is below the restart level. Before coding this macro, it is recommended that you read about the communications control program in TPF Non-SNA Data Communications Reference.

This macro need not be coded if the default values are acceptable. SIP automatically assigns these values if the macro is omitted although a warning message is issued. These values are stored in keypoint A (CTKA).

The CCPPOL macro is coded when generating a 'base only' system or when generating the basic subsystem in a multiple database function (MDBF) environment.
