In cobol, there is no need to pass the lenght of the (passing) variable. So parm-data1 value should come from the called program. I stand with William to predict the value. Only thing I can say, it should fall between -32768 through +32767. |

Now, if you really meant:
LINKAGE SECTION.
01 jcl-parm.
05 parm-data1 PIC S9(4) COMP.
05 aprm-data2 PIC X(4).
Then parm-data1 would contain the length of the parm value on the EXEC card, which should be at least 4 but might be longer or shorter. |

This is fine for CICS COBOL program. For a general cobol program, is not the calling program should pass the value betewen -32768 to +32767? |

Huh? Between the clues of "Post subject: linkage section", "Forum Index -> Mainframe COBOL" and "parm-data1 and parm-data2"........  |

| William - excellent clarification, but why should the EXEC PARM be at least 4 in length? |

Only "should", since it looks like he is intending to access up to four bytes and good practice is that you only access memory that is yours to access..... |
