NAME

f77 - Fortran compiler.

SYNOPSIS

f77 [options] file ...

DESCRIPTION

f77 is an AmigaDOS frontend for the port of the AT&T Laboratories and Bellcore f2c Fortran to C translator that works with the SAS AmigaDOS C compiler version 6.51. It tries to give the impression of a true Fortran compiler for AmigaDOS. The frontend accepts the following types of file arguments:

Arguments that end with .f are compiled as Fortran 77 source files. If each source compiles successfully, its corresponding object file is left in the current directory in a file whose name is that of the source, with .o substituted for .f.

Arguments that end with .c are assumed to be C source files, and are compiled, producing .o files.

Arguments that end with .o are passed on to the linker (see the SAS documentation for slink) to be linked into the final program.

Arguments that end with .lib are taken to be standard AmigaDOS linker libraries of .o files to be searched in the order they appear.

f77 accepts the following options:

+B: Treat the backslash character as a C-like escape character.
-C: Enable array subscript range checking.
-c: Suppress linking and produce an object (.o) file from each source file.
-g: Generate information needed by the symbolic SAS CodeProbe debugger.
-I2: Make default size of integers and logicals INTEGER*2 and LOGICAL*2.
-I4: Make default size of integers and logicals INTEGER*4 and LOGICAL*4.
-l name: Search the library lib:name.lib. Libraries specified by this option is searched after the ones given directly.
-noext: Do not accept any extensions to Fortran 77, like DO - END DO.
-O: Enable the SAS C global optimizer.
-o outfile: Name the output file resulting from linking outfile instead of the default file name a.out.
-onetrip: Execute any DO loop at least once.
-S: Translate the named Fortran source files and leave the C language output in corresponding files whose names are suffixed with .c (no .o files are created).
+U: Distinguish uppercase and lowercase (make case significant). Keywords must be lowercase.
-u: Force types of identifiers to be implicitly undeclared (same as specifying IMPLICIT NONE).
-v: Enable the verbose mode, producing a step-by-step description of the compilation process. This may generate a lot of noise.
-w: Suppress all warning messages from f2c .
-w66: Enable warnings about Fortran 66 features used.
