DEQC-Dequeue from Resource

Use this general macro to inform the control program that the entry control block (ECB) has finished with a shared resource. The DEQC macro is used with the ENQC or SANQC macro.

Format




label
A symbolic name can be assigned to the macro statement.

BLOCK=address
If specified, this is the address of an 8-byte area that contains the name of the resource on which the ECB was enqueued using the ENQC or SANQC macro. BLOCK and LEVEL are mutually exclusive.

LEVEL=Dx
If specified, this is a file address reference word (D0-DF) that contains the name of the resource on which the ECB was enqueued using the ENQC or SANQC macro. BLOCK and LEVEL are mutually exclusive.

QUAL
Subsystem qualification for the resource. The default value is U.

U
Subsystem qualification applies. The resource name is subsystem unique and is qualified by the Data Base Index (DBI) value for the subsystem.

S
Systemwide qualification applies. The resource name is not subsystem unique; that is, all ECBs in the TPF system that issue a SANQC or ENQC macro with the same resource name and QUAL=S coded are enqueued on the same resource. If two SANQC or ENQC macros are issued with the same resource name but different QUAL values coded, two different resources are assumed to exist. The SANQC or ENQC macro and its corresponding DEQC macro must have the same QUAL value coded.
