Error message

C LANGUAGE STACK BLOCK RELEASE ERROR

Explanation

Attempts to release the IBM® C language stack blocks during SWISC, ENTDC, or EXITC maro processing failed. This message will follow a 0006DA system error, which indicates a block release error. A failure to release IBM C language stack blocks is usually the result of block corruption.

System action

The entry control block (ECB)is ended and a dump of the ECB and working storage is generated. No other IBM C language stack blocks attached to this ECB are released, therefore those blocks can no longer be used by the z/TPF system. Immediately prior to the system error routine, register 1 is set up to contain the address of the block that could not be released.

User response

Do the following:
  1. Review the system error dump to determine the cause of the error.
  2. Correct the error.
