Sheltran - CALL statement

Within the CALL argument list statement label arguments may be replaced by one of the same keywords for I/O statements. Such arguments must be preceded by an asterisk (*). E.g.

      CALL sub ( ..., *XWHILE, ... )

Notes:

This feature can only be used in calls to existing FORTRAN subroutines that specify alternate returns. The designers of SHELTRAN consider this feature undesirable and only provided an interface to existing routines, but have intentionally omitted the facility to construct them, i.e. the 'RETURN i' statement is not allowed.
Asterisk arguments must appear on the first line of the CALL statement.
