Hi all,
let us say if Iam reading a file (say xfile) of 192 bytes. The copybook has the following structure.

01 X pic x(192)

01 Y redefines X.
05 rectype pic X(2).
88 type1 value '01'.
88 type2 value '02'.
88 type3 value '03'.
05 recdata pic x(190).

Suppose if I have the statement
Read xfile into X
Then, can I issue a statement like
If type1 perform process-para.
My actual doubt is when we are reading into X can we check a record of Y but redefined to X ? Please clarify. thanks in advance.

Hi Chandra,

Yes u can .

Because the area occupied by a field in a COBOL layout can be re-used for different data by redefining the original field. This does exactly what it says -- it redefines the space used by a field for another use.

Hi !

You could also use:

Evaluate true
When Type-1 Perform Process-1
When Type-2 Perform Process-2
When Type-3 Perform Process-3
When Other Continue
End-Evaluate
