FORTRAN
With this option you can include messages, flags, and conditional branches to
help you trace program execution and find an error.
/[NO]OPTIMIZE
(FORTRAN–77 only) /OPTIMIZE enables compiler optimization (the default).
/NOOPTIMIZE inhibits compiler optimization.
/RECORD:length
Overrides the default maximum record length for sequentially formatted input
and output. The meaningful range for length is from 4 to 4095.
For FORTRAN IV, the default maximum record length is usually 132 characters,
while for FORTRAN–77 the default length is usually 136.
/SHOW[:type]
Specifies listing options. The type argument specifies a code indicating the kind
of listing the compiler is to produce.
The following table summarizes the FORTRAN IV listing options.
FORTRAN IV Listing Options
Type Code Option Listing
0 Diagnostics only
1 or SRC Source program and diagnostics
2 or MAP Storage map and diagnostics
3 Diagnostics, source program, and storage map
4 or COD Generated code and diagnostics
7 or ALL Diagnostics, source program, storage map, and generated code
You can combine FORTRAN IV listing options by specifying the sum of their
numeric codes. For example, the following two options have the same meaning:
/SHOW:7
or
/SHOW:ALL
If you specify no code, the default value is 3, a combination of SRC and MAP.
With FORTRAN–77, the codes for the type argument are 0 through 3; the
following table describes the meaning of each FORTRAN–77 code.
