XOPEN #ch, fspec, mode, flags
This is equivalent to the traditional OPEN statement for ISAM files, except:
• | XOPEN eliminates the implicit connection between the fstat and recno variables normally specified in the OPEN, and the file access statements. The recno and fstat parameters are eliminated. |
• | XOPEN allows for the various flags (WAIT'RECORD, WAIT'FILE, END'FILE,...) which must normally be specified as literals to the compiler to instead be evaluated at runtime. |
The values for flags are:

* These are the literal file OPEN modifiers that can be tacked on to the end of an ISAMA OPEN statement.
