Updates to PIPEDEMO are shipped in CMS UPDATE format.
Doug Dean - aka Doug_Dean@Sterling.COM - made some changes to PIPEDEMO and introduced this update scheme.
The updates are based on a certain version, which should be on one of the accessed disks and named PIPEDEMO $EXEC. PDUPDT EXEC applies the updates. It checks for the presence of PIPEDEMO $EXEC. If it is not found, PDUPDT tries to create the $EXEC from your PIPEDEMO EXEC. The validity of the $EXEC is checked in the update process. If you get errors, then first try to erase the $EXEC and let PDUPDT decide whether your running version of PIPEDEMO can be used as the base. If this also fails, please retrieve PIPEDEMO $EXEC.
As of now there are 4 updates, which are based on PIPEDEMO 3.1.1. To reconstruct the EXEC with the changes simply enter the following at the CMS command line:
pdupdt
To add more updates to this exec, add update lines to PIPEDEMO UPDTLIST in order after UPDT3104, e.g.:
PIPEDEMO UPDT3101
PIPEDEMO UPDT3102
PIPEDEMO UPDT3103
PIPEDEMO UPDT3104
PIPEDEMO Update number 5
(etc.)
PDUPDT uses this simplified scheme instead of the standard CMS UPDATE procedure.
