MBCS
NOMBCS
MIXED
NOMIXED
Specifies sequences of characters,
known as trigger constants, that
identify comment lines as compiler
comment directives.
Default: Comment lines beginning
with IBM* are considered
directives. If you specify
-qsmp=omp, only $OMP is
considered to be a directive trigger.
All other directive triggers are
turned off unless you explicitly
turn them back on. If you specify
-qsmp=noomp (noomp is the
default for -qsmp), IBMP, $OMP
and SMP$ are considered directive
triggers, along with any other
directive triggers that are turned on
(such as IBM* and IBMT). If you
have also specified -qthreaded,
comment lines beginning with
IBMT are also considered
directives.
Indicates that the input source
program is in fixed source form
and optionally specifies the
maximum line length.
Default: -qfree=f90 for the f90, f95,
xlf90, xlf90_r, xlf90_r7, xlf95,
xlf95_r, and xlf95_r7 commands
and -qfixed=72 for the xlf, xlf_r,
xlf_r7, and f77/fort77 commands.
Indicates that the source code is in
free form. The ibm and f90
suboptions specify compatibility
with the free source form defined
for VS FORTRAN and Fortran
90/Fortran 95, respectively. -k and
-qfree are short forms for
-qfree=f90.
Default: -qfree=f90 for the f90, f95,
xlf90, xlf90_r, xlf90_r7, xlf95,
xlf95_r, and xlf95_r7 commands
and -qfixed=72 for the xlf, xlf_r,
xlf_r7, and f77/fort77 commands.
Indicates to the compiler whether
character literal constants, Hollerith
constants, H edit descriptors, and
character string edit descriptors can
contain Multibyte Character Set
(MBCS) or Unicode characters.
Default: -qnombcs
Makes the compiler sensitive to the
case of letters in names.
Default: -qnomixed
