C_LOC and character string
I think this is a standard complaint code and about as simple as it gets, but the xlf2003 compiler gives the error: "test.f90", line 19.15: 1516-169 (S) A variable that is specified as an argument to the intrinsic procedure C_LOC must either have type and type parameters that are interoperable with a C type, or ... 2 Apr 2010 11:29

Output units nowadays
This is purely a theoretical issue for me, not a practical one, but I'm interested in it, for curiosity's sake. Imagine a modern workplace ... pc, win/linux (whatever fits you the most), modern printer and so on. Nowadays, when we use output units we usually mean either output to file (number), or to screen (us... 31 Mar 2010 05:26

Can command characters actions be disabled in modern compilers ?
Simple question really; is there an option which disables command characters actions (1,0,+ or blank in column 1) in either Intel's or gfortran's line of compilers ? If I understood correctly, they're deleted out of f2003 (or have I misread ?). pp, Luka ... 31 Mar 2010 08:43

Fortran 95 equivalent of read(..., POS=...)
I am trying to compile a fortran 2003 code using a fortran 95 compiler. The only '03 feature the code has is this ONE line: read(f, pos = <foo>) <var> One line. I'm trying to avoid having to install an 03 compiler (and other intermediary wrappers etc) just for this. The last time I used fortran it was on 77, ... 30 Mar 2010 14:58

Calling DLL subroutine from C++
I am able to invoke a subroutine in my DLL successfully, and all seems OK until the execution is complete. On return from the DLL subroutine my C++/Qt application crashes silently. My subroutine expects an integer and four character arrays: subroutine execute(ncpu,infile,outfile,resfile,runfile) !DEC$ ATTRI... 29 Mar 2010 19:12

Does this make any sense to anyone ?? 2) Apart from temporarily suspending the program execution, DOES Pause do... 3 Apr 2010 07:09
