Control-list parameters can be specified in the following forms:
The nonkeyword form of the direct-access record specifier must immediately follow the nonkeyword form of the logical unit specifier.
When used with a logical unit specifier or internal file specifier, the nonkeyword form of the format or namelist specifier must occupy the second position in the control list. The unit or internal file specifier must also be in nonkeyword form (and occupy the first position in the control list).
