Retries on an EXEC CICS LINK command
If the external CICS® interface receives a RETRYABLE response on an EXCI call that it makes on behalf of an EXEC CICS LINK command, it automatically retries the EXEC CICS LINK command up to five times, providing more serious errors do not occur.
If the RETRYABLE response is still received after the fifth retry, the RESP field is set to LINKERR, and the reason returned on the EXCI CALL request that causes the exception is returned in the RESP2 field.
The external CICS interface retries the EXEC CICS LINK command by first closing and deallocating the pipe, then reissuing the six EXCI CALL commands. During Allocate_Pipe processing, the EXCI CALL interface calls the user-replaceable module, DFHXCURM, to give you the opportunity to change the APPLID of the CICS system to which the request has been sent. See The EXCI user-replaceable module for details of DFHXCURM.

| 414 | If run as a CICS-to-CICS linked-to program, this server program would have resulted in an error with an appropriate message sent to the terminal. Running the program as an EXCI server program returns the message addressed by the MSGPTR field of the RETCODE area. | |

| 416 | Command has been issued against a CICS region running under a release of CICS earlier than CICS for MVS/ESA 4.1 | |
| 417 | Command has been issued against a pipe in the MUST CLOSE state. Further EXCI EXEC CICS LINK commands will have unpredictable results and are, therefore, not permitted | |
| 418 | Pipe_token does not address an XCPIPE control block, or there is a mismatch between user_token and pipe_token | |
| 419 | CICS runs, or did run, under the TCB that this command is attempting to use. This is not permitted and the command fails | |

| 620 | IRP has disconnected from EXCI | |
| 621 | A DISCONNECT command is issued in an error situation following an IRP CONNECT. The DISCONNECT has failed, indicating a serious error. | |
| 622 | XCPRH ESTAE setup command failed This error leads to user abend 402. | |
