A diagnostic message issued by the compiler describes the detected
error and, in some cases, contains an indication of the action
taken by the compiler in response to the error.
Besides reporting errors detected in source program syntax, the
compiler issues messages indicating errors that involve the
compiler itself, such as I/O errors.
The severity-level classes of compilation error messages, in order
of greatest to least severity, are as follows:
Code Description
---- -----------
F Fatal; must be corrected before the program can
be compiled. No object file is produced.
E Error; should be corrected. An object file is
produced, but the output or program result may
be incorrect.
W Warning; should be investigated by checking the
statements to which warning diagnostic messages
refer. Warnings are issued for statements that
use acceptable, but nonstandard, syntax and for
statements corrected by the compiler. An object
file is produced, but the program results may be
incorrect. (If you specify /NOWARNINGS on the
FORTRAN command line, you will not receive these
messages.)
I Information; not an error message and does not call
for corrective action. However, the informational
message informs you that either a correct Compaq Fortran
statement may have unexpected results or you have
used a Compaq Fortran extension to FORTRAN-77.
The following examples show how compilation messages are displayed:
%FORT-W-FMTEXTCOM, Extra comma in format list
[FORMAT (I3,)] in module MORTGAGE at line 13
%FORT-F-UNDSTALAB, Undefined statement label
[66] in module MORTGAGE at line 19
