Types of Data

This COBOL system always allocates the same number of bytes to a data item as in the original program, but might redefine its contents when it is converted. Therefore, you must be aware that if these items are redefined, and the program logic expects to find a certain binary value in the redefinition, you might not receive the behavior you are expecting at run time. At run time, this COBOL system might treat the ON SIZE ERROR clause differently from the RM/COBOL system. See the chapter RM/COBOL Conversion Issues for further details.

The following sections define how this COBOL system treats COMPUTATIONAL, COMPUTATIONAL-1 and COMPUTATIONAL-6 types of data.
