Process names

Architected process names are one through four bytes long, and have a first byte value that is less than X'40'.

In CICS, the names are specified as four-byte hexadecimal transaction identifiers. If CICS receives an architected process name that is less than four bytes long, it pads the name with null characters (X'00') before searching for the transaction identifier.

CICS supplies the processes shown in Figure 1.
