<H2>Option: <font color=#FF0080>check</font></H2><P>
<A NAME="check"></A><DT><B><A HREF="check.html">-check</A></B> </DT>
<DD>This switch is provided so
that errors and warning messages can be turned off when <B>ftnchek </B> is used
for purposes other than finding bugs, such as making declarations or printing
the call tree. It is positional, so after turning all checks off, selected
checks can be turned back on. The effect of <B>-nocheck </B> is to put all switches,
numeric settings, and settings controlling lists of warnings to their
turn-off values, as if they had all been specified with the -no prefix. Switches
and settings that specify options and modes of operation, rather than
controlling warnings, are unaffected. These are <B><A HREF="columns.html">-columns</A> </B>, <B><A HREF="include.html">-include</A> </B>, <B><A HREF="intrinsic.html">-intrinsic</A>
</B>, <B><A HREF="library.html">-library</A> </B>, <B><A HREF="makedcls.html">-makedcls</A> </B>, <B><A HREF="output.html">-output</A> </B>, <B><A HREF="pointersize.html">-pointersize</A> </B>, <B><A HREF="project.html">-project</A> </B>, <B><A HREF="quiet.html">-quiet</A> </B>, <B><A HREF="source.html">-source</A>
</B>, <B><A HREF="version.html">-version</A> </B>, <B><A HREF="wordsize.html">-wordsize</A> </B>, and <B><A HREF="wrap.html">-wrap</A> </B>. Default = yes. <blockquote></DD>
</DL>
<P>
Parse errors (syntax
errors due to unrecognized or malformed statements) are not suppressed
by this switch, since the results may be incorrect if <B>ftnchek </B> has not
parsed the program correctly. <P>
There are some miscellaneous errors and warning
messages that are not controlled by any other switch, and so can be turned
off only by this switch. Note that using <B><A HREF="check.html">-check</A> </B> following <B>-nocheck </B> only
has the effect of turning these special warnings back on, and does not
restore all the checks it turned off. These warnings are:
<DL>
<DT>o </DT>
<DD>Module contains
no executable statements. </DD>
<DT>o </DT>
<DD>Zero or negative length specification in a
data type declaration of the form type*len. </DD>
<DT>o </DT>
<DD>Array assigned to scalar.
</DD>
<DT>o </DT>
<DD>Type mismatch between DO index and bounds. </DD>
<DT>o </DT>
<DD>Undefined common block
declared in SAVE statement. </DD>
<DT>o </DT>
<DD>Intrinsic function explicitly declared
with an incompatible type. </DD>
<DT>o </DT>
<DD>Unknown intrinsic function explicitly declared
in an INTRINSIC statement. </DD>
<DT>o </DT>
<DD>Intrinsic function passed as a subprogram
argument is not declared in an INTRINSIC statement. </DD>
<DT>o </DT>
<DD>Intrinsic function
or statement function invoked incorrectly. </DD>
<DT>o </DT>
<DD>Function does not set return
value prior to RETURN statement. </DD>
<DT>o </DT>
<DD>Parameter constant value not evaluated
(this is <B>ftnchek </B>'s fault, and it is just informing you of the fact). </DD>
<DT>o
</DT>
<DD>Entry point of a subprogram is later used as a different subprogram's
name. </DD>
<DT>o </DT>
<DD>Unknown keyword used in an I/O statement. </DD>
