–nocpp Does not run the C preprocessor on the source files.
Specifying this option allows you to specify C-style
comments inside Hollerith strings. Use this option when
you want your program to strictly conform to the Fortran 77
standard.
–noexpopt Excludes floating point constant exponent optimization to
achieve the same precision as releases prior to 4D1-4.0.
–noextend_source
Sets the source statement format as described in Table 1-5.
If the source statement contains fewer than 72 characters,
blanks are assumed at the end; the ability of TAB-formatted
lines to extend past Column 72 is disabled.
This option provides VMS Fortran default mode.
–noi4 Same as –i2 option.
–nof77 Same as –onetrip switch except for the following:
• The syntax and behavior of EXTERNAL statements are
altered.
• The default value for the BLANK= clause in an OPEN
statement is ZERO.
• The default value for the STATUS= clause in an OPEN
statement is NEW.
–noisam Excludes the indexed sequential access library libisam.a
from being linked to the executable to reduce the size.
