G77 binary file access

G77 binary file access

[Lichtenberger Janos]

Hello,

Is it possible to open raw binary file (i.e. without any record structure) 
with G77 OPEN statement or the fputc/fgetc is the only (not very comfortable) 
way to acces raw data.
In other Fortran dialects (like DEC, SGI IRIX, or Microsoft for PCs :-)) there 
are additional options to ANSI FORTRAN 77 of OPEN statement, like 
form='binary' or access='stream'. I have not found any suitable set of options 
for this purpose. Can you help me?


Best regards,


Janos Lichtenberger

No, with g77 you have the following options:

1. Use fputc/fgetc (as above).
2. Use a direct access file with RECL=1 and read every character as
   a single byte "record".

Sorry, no other options than the above ...

Kind regards,
