VSM-2850-00-E AMB VSAM error - when reqid keyword is used with the PERFORM option of &ampVS-ENDBR-UNLOCK-LOGIC all applicable commands must have the REQID keyword

The REQID was used previously in the program but was not specified for this call. The control variable &VS-ENDBR-UNLOCK-CONTROL is set to PERFORM (versus INLINE).
Restriction: This topic applies only when the AppMaster Builder AddPack has been installed, and applies only to Windows platforms.

Resolution:

Code the REQID keyword on all applicable calls or change the value of &VS-ENDBR-UNLOCK-LOGIC to INLINE in APSCNTL(APVSAMIN).
