Aninternalfile is an object of typeCHARACTERsuch as a variable, substring, array, element of an array, or field of a structured record. Internal fileREADcan be from aconstantcharacter string. I/O on internal files simulates formattedREADandWRITEstatements by transferring and converting data from ...

The format code F (and similarly D, E) has the general form Fw.d where w is an integer constant denoting the field width and d is an integer constant denoting the number of significant digits. For integers only the field width is specified, so the syntax is Iw. Similarly, character ...
The type of a variable, named constant or function, is, by default, determined by the initial letter of its name: integer if it is i, j, j, 1, m, or n and real otherwise. However, it is more usual to specify the type explicitly with a type statement: Sign in to download full...
Allow a subprogram to change a dummy argument that is a constant. This option is provided only to allow legacy code to compile and execute without a runtime error.Without -copyargs, if you pass a constant argument to a subroutine, and then within the subroutine try to change that constant...
Details concerning environment-specific values and defaults and system-specific features or limitations are presented in the release notes delivered with the PGI Visual Fortran. Conventions This guide uses the following conventions: italic is used for emphasis. Constant Width is used for filenames, ...
