Doudt Regarding Linkage Variables.

Hi,

I have a doudt regarding the Variable passing from a main standalone progam to a sub routine.

There was a copy book in the Working storage of the main program. All the variables in the copybook have a "VALUE" clause.

There was a process to manipulates these variables in the main program before a call to the sub program

In the linkage section of the sub routine, the same copybook is present with the same 'VALUE' clause.

My doudt is ..what values does the copybook variables will have. Is that what the 'VALUED' clause declared in the linkage copybbok or the values pased thru the main program.

Hi,

It will have the values passed thru the main program.

Hi,

I also think it will contain manipulated valuesmeans the value which is passed by main pgm.

hi guptae/sarun,

Giving Value clause for a variable means Initialization.
I couldn't map ......the reason y the values from main program where passed to sub routine

Hi Vamsi,

I think the value passed by the program will override the value which is give in linkage section

Hi Vasmi,

Value clause format :-

Format 1

--------

VALUE {IS} literal

Format 2

--------

88 condition-name VALUE/VALUES {IS/ARE}

literal1 {THROUGH/THRU} literal2

You should not give a value clause of format 1 type for a variable in Linkage section. Only Format 2 VALUE clauses may be coded in the FILE and LINKAGE SECTIONS. As an IBM extension, Format 1 VALUE clauses coded in the FILE and LINKAGE SECTIONS are treated as comments.
