As vendor extension, the +dollar sign (<code>$</code>) is additionally permitted with the option +<samp>-fdollar-ok</samp>, but not as first character and only if the +target system supports it. +</p> +<p>By default, the procedure name is the lower-cased Fortran name with an +appended underscore (<code>_</code>); using <samp>-fno-underscoring</samp> no +underscore is appended while <code>-fsecond-underscore</code> appends two +underscores. Depending on the target system and the calling convention, +the procedure might be additionally dressed; for instance, on 32bit +Windows with <code>stdcall</code>, an at-sign <code>@</code> followed by an integer +number is appended. For the changing the calling convention, see +see <a href="GNU-Fortran-Compiler-Directives.html#GNU-Fortran-Compiler-Directives">GNU Fortran Compiler Directives</a>. +</p> +<p>For common blocks, the same convention is used, i.e. by default an +underscore is appended to the lower-cased Fortran name. Blank commons +have the name <code>__BLNK__</code>. +</p> +<p>For procedures and variables declared in the specification space of a +module, the name is formed by <code>__</code>, followed by the lower-cased +module name, <code>_MOD_</code>, and the lower-cased Fortran name. Note that +no underscore is appended. +</p> + + + + +</body> +</html> |
