General Compiler Directive: STRICT disables language features not found in the language standard specified on the command line (Fortran 2003, Fortran 95, or Fortran 90). NOSTRICT (the default) enables these features.
cDEC$ STRICT
cDEC$ NOSTRICT
c |
Is one of the following: C (or c), !, or *. (See Syntax Rules for Compiler Directives.) |
If STRICT is specified and no language standard is specified on the command line, the default is to disable features not found in Fortran 2003.
The STRICT and NOSTRICT directives can appear only appear at the top of a program unit. A program unit is a main program, an external subroutine or function, a module, or a block data program unit. STRICT and NOSTRICT cannot appear between program units, or at the beginning of internal subprograms. They do not affect any modules invoked with the USE statement in the program unit that contains them.
