The picture and usage description must conform to ANSI-COBOL 85 specifications. For information about COBOL picture strings, see the documentation for the COBOL compiler.
The picture description must match the record file descriptor (FD) from the COBOL program that generates or will use the data. For information on COBOL formats, see your COBOL programmer's manual.
The usage description must match the data-field type described in the FD descriptor of the COBOL program. If the COBOL program does not include a usage clause, select the Chars (character) option for the usage.
When values are converted to packed-decimal formats, supply a picture clause that matches the picture clauses in the COBOL programs that use the data. Otherwise, the COBOL interpretation of the values will be wrong.
The following table lists some examples of appropriate picture clauses.
