I have seen this question in many interview dumps? can someone answer that is it possible to redefine a COBOL variable to a larger size?
For example:
Can we
10 VAR1 PIC X(100).
10 VAR2 REDEFINES VAR1 PIC X(200).
Is the above possible?
it is possible
Some versions of some compilers will allow this with no problem.
Some will issue a Warning.
Some will raise an Error and the compile will fail.
Suggest one read the manual for the compiler and version being used.
