Applications
-[no]extend_source [size]
Default: -noextend_source, which implies 72 characters; if -extend_source
is specified without a size, the default becomes -extend_source:132
Alternate syntax: -{72|80|132}
Specifies the column number used to end the statement field in fixed-form source
files: 72, 80, or 132. When a size is specified, that will be the last column parsed
as part of the statement field. Any columns after that will be treated as
comments.
This option is valid only for fixed-form files, and it enables the -fixed option.
-[no]f66
Default: -nof66 (use current Fortran standards semantics)
Alternate syntax: -66
Specifies that the compiler should select FORTRAN-66 interpretations in cases
of incompatibility. Differences include the following:
• DO loops are always executed at least once
• FORTRAN-66 EXTERNAL statement syntax and semantics are allowed
• If the OPEN statement STATUS specifier is omitted, the default changes
to STATUS='NEW' instead of STATUS='UNKNOWN'
• If the OPEN statement BLANK specifier is omitted, the default changes to
BLANK='ZERO' instead of BLANK='NULL'
-[no]free or -[no]fixed
Default: File extension is used to determine format.
Alternate syntax: -FR is equivalent to -free; -FI is equivalent to -fixed.
Specifies the format of the Fortran source code. If this option is not specifed, the
file extension determines the format:
• Files with an extension of .f90, .F90, or .i90 are free-format source
files.
• Files with an extension of .f, .for, .FOR, .ftn, or .i are fixed-format
files.
