Customer asked about CCW with EXCP usage by MIM.
1 Does MIM use CCW with EXCP ?
2 Does MIM use a file to be open as INPUT and use the file as OUTPUT in subsequent process ?
MIM uses OPEN/SVC 19 with the UPDATE option(not INPUT) when opening the DASD control files and checkpoint files.
MIM uses EXCP/SVC 0 when reading/writing to the DASD control files and checkpoint files.
