CA IDMS Masterkey extends the capabilities of the CA IDMS/DC CLIST processor.
Without CA IDMS Masterkey, CLISTs can only be chained. If CLIST A contains an invocation of CLIST B, control is transferred to CLIST B without a subsequent return to CLIST A. Consequently, any other statements in CLIST A that follow the invocation of CLIST B would not be executed.
If the CLIST in Exhibit 2.2 were to be executed without CA IDMS Masterkey, the commands OLM and ADSC would be dropped.
In contrast, OLM and ADSC would be executed in CA IDMS Masterkey because it nests CLISTs. When CLIST A invokes CLIST B, control returns to CLIST A and execution continues. All statements of all CLISTs in an execution hierarchy are performed as if each CLIST was independently executed.
