Does anyone have a list of COBOL statements that do not allow the use of a data-name reference by a subscript. I want to create a recommendation on how, and where to use subscripted data-names.

Example: valid usage

SELECT OPTIONAL "file-name-1" ASSIGN "assignment-name-1" TO LINE SEQUENTIAL ORGANIZATION IS ACCESS SEQUENTIAL MODE IS " STATUS FILE IS "data-name-1".

Where as the data-name-1 is table-element (table-subscript-1). This look dangerous to code a statement like this, because the subscript must have a valid value before this file can be open or it will generated an run time error.
Does anyone know if the compiler will allow this statement? icon_eek.gif

Have you tried this? If not, do so and post anything that happens that is not clear.

The Language Reference for your compiler is the best source for this kind of info.

Possibly there is something i misunderstand, but i do not understand how such a recommendation would be created. Anything that occurs multiple times must be so referenced, regardless of any recommendation icon_confused.gif As i mentioned, there may be something i misunderstand.
