Description |
-1 |
Same as -onetrip. |
-132 |
Enables fixed form source lines to contain up to 132 characters. |
-ansi[-] |
Enables (default) or disables assumption of the program’s ANSI conformance. |
-dps , -nodps |
Enables (default) or disables DEC* parameter statement recognition. |
-extend_source |
Enables extended (132-character) source lines. Same as -132. |
-FI |
Specifies that all the source code is in fixed format; this is the default except for files ending with the suffix .f, .ftn, .for. |
-FR |
Specifies that all the source code is in Fortran 90-95 free format; this is the default for files ending with the suffix .f90. |
-lowercase |
Default. Changes routine names to all lowercase characters. |
-nbs |
Treats backslash (\) as a normal graphic character, not an escape character. This may be necessary when transferring programs from non-UNIX environments, for example from VAX-VMS. For the effects of the escape character, see the Escape Characters. |
-nus[file] |
Do not append an underscore to subroutine names listed in file. Useful when linking with C routines. |
-onetrip |
Compiles DO loops at least once if reached (by default, Fortran 95 DO loops are not performed at all if the upper limit is smaller than the lower limit). Same as -1. |
-pad_source |
Enforces the acknowledgment of blanks at the end of a line. |
-uppercase |
Maps routine names to all uppercase characters. Note |
-vms |
Enables support for extensions to Fortran that were introduced by Digital VMS Fortran compilers. The extensions are as follows:
