Hai,
Linkage Section.
01 Parmfield.
02 parm-data pic x(20)
02 parm-length pic s9(4) comp.
Here what will be the value of parm-length before the execution.?
and value if no data passed through PARM parameter in JCL?
Will it create any error? |

OK, so I am not a programmer, so someone will possibly let me know if I am wrong
1) I thought that the length of the parm field was the first 4 bytes of the PARM field defined to WS.
2) Can not ever recall it being signed, but then .......................
3) Here what will be the value of parm-length before the execution.? -- Technically speaking it won't exist before execution
4) Hazard a guess at a big fat zero
5) Will it create any error? -- Why have you not tried any of this for yourself before posting ? |

Hi Expat,
No, you are not wrong.
This topic (and a couple others) are quite possibly mis-worded interview questions. |

expat,
first 2 bytes (PIC 9(4) comp.) of parm defined in linkage.
other than that, great answer.
this is the 3rd of these type of rookie questions that I have seen today on the board. 'print without dd', 'which record will be read', and this silliness.
all three of these threads should be in interview forum; or has this website decided to dumb-down the technical forums? |
