Hi,
Can anyone let me know what happens to the calling program that issues
EXEC CICS XCTL command.
Will the program still remain in normal execution of the statements given after XCTL or will it b loaded off the memory as soon as XCTL is issued ?
Regards, |

Hello,
The program that issues the XCTL is not a "calling program". An XCTL is more like a "go to" than a perform. Control does not automatically return to the program that XCTLs another.
It may or may not be "loaded off" immediately. |

Hi,
So does that means that once we XCTL, the main program does not executes the code after the XCTL command ? Or will both the programs coexist and the main program will still perform the things after the XCTL command ?
Thanks for you reply sir. |

From the CICS Language Reference (link at the top of the page) on XCTL:
| Quote: |
| XCTL transfers control from one application program to another at the same logical level. The program from which control is transferred is released. If the program to which control is transferred is not already in main storage, it is loaded. |
Released means gone ... no longer running ... transfer control means what it implies: the program control is transferred to starts running, the program control is transferred from has finished and is no longer running. Any commands after the XCTL will not be executed. |

Yes.

No, for that you would need something like a START..... |
