Looking for a Fortran 77 or newer compiler fo PC
Well it looks like only integer variables are allowed in DATA statements. I guess maybe what I had was an extension to the F77 standard? Oh well I can work around it. An it's probably time to let this topic expire. Thanks very much for the help offered here! [smile] -
Looking for a Fortran 77 or newer compiler fo PC
Nope. Distilled to simple program: PROGRAM FOO CHARACTER*1 ESCAPE DATA ESCAPE/Z'1B'/ END Compile with: gfortran -c -g -S -ffixed-line-length-none -fno-align-commons -fallow-invalid-boz -std=legacy Still get: Error: BOZ literal constant cannot be assigned to a 'CHARACTER(1)' variable -
Need a 2D vector graphics package
I'm breathing life back into a program I wrote years ago. It used a graphics software called GKS. Anyone know of something similar? -
Looking for a Fortran 77 or newer compiler fo PC
Nope. Rename didn't help. I found that the error is due to the data assignment, not the ! comment. CHARACTER*1 ULA, URA, DLA, DRA, ESCAPE DATA ESCAPE/Z'1B'/ The above is supposed to assign the hex value for Escape which is 1B (or 33 octal or 27 decimal) to the variable ESCAPE. Instead I get... -

Sorry - COMPASS.IN contains: CHARACTER*1 UP, DOWN, LLEFT, RRIGHT CHARACTER*1 ULA, URA, DLA, DRA, ESCAPE DATA ESCAPE/Z'1B'/ DATA UP/Z'17'/ DATA DOWN/Z'1A'/ DATA LLEFT/Z'19'/ DATA RRIGHT/Z'18'/ DATA ULA/Z'5C'/ ! Up left angle DATA URA/Z'5D'/ ! Up right angle DATA DLA/Z'5E'/ ! Down... -

I'm using .for for a source file extension. The error message I get is: COMPASS.IN:12:20: 12 | DATA DRA/Z'5F'/ ! Down right angle | 1 Error: BOZ literal constant near (1) cannot be assigned to a 'CHARACTER(1)' variable... -
Looking for a Fortran 77 or newer compiler fo PC
My old F77 source has comments on individual lines like: DELIM = DELIM_LIST(K) ! Get delimiter Not possible with gfortran? No big deal but if there is another magic switch, yay! -
Looking for a Fortran 77 or newer compiler fo PC
Hey that worked! Thanks. That business with 2 kinda rings a bell with me. Standard out & standard error? Used to manage a bunch of Unix servers back in the 90's. Been a long time. I made a batch file (macro) to compile in DOS. echo off gfortran -c -S -ffixed-line-length-none -std=legacy %1 2> %1.err -

Still don't see how to direct compiler error reporting to a file... -
Looking for a Fortran 77 or newer compiler fo PC
Aha! With a little poking I found gfortran --help. The trick is two dashes... The -S switch (option) lets me keep the assembler code - yum! -
Looking for a Fortran 77 or newer compiler fo PC
Thanks mikrom et al. The -c switch does the trick. I looked all over for that kind of info but no luck. I ask here when I hit a wall. I bet there are other switches like error output redirect. Can you point me to a document that covers this? I just found a man page for gfortran but I don't see... -
Looking for a Fortran 77 or newer compiler fo PC
Thanks all for the info. I installed the gfortran compiler and am using it via command line. I'm getting strange errors using gfortran -std=legacy. It looks like the compiler is building an exe by default and wants all subroutines specified. That means all modules must be specified on the... -
Looking for a Fortran 77 or newer compiler fo PC
Hi I'm new here and hope this isn't a question beaten to death. I'm thinking about getting back into Fortran and would like to find a compiler that works on Windows 64 bit. By compiler, I mean something that compiles the source, generates binaries and then an executable. I would prefer something...
