HELP PLEASE g77 0.5.23 or ver.2.90.23 (980102)

Hello, I have a program that needs g77 ver.0.5.23 or ver.2.90.23 (980102) to compile DO loops correctly. (While Linux fort77 ver.1.14a also compiles DO loops correctly but has other problems. Linux compiler g77 ver.0.5.24 or ver.2.91.66 (981002) (and many other versions) does not write files correctly).
I have read that g77 is old and will mess up my opensuse 11.4.
What compiler should I install?

Have you looked at the package gcc33-fortran from the standard
repositories? The executable is named /usr/bin/g77-3.3

openSUSE 11.4 is also old :wink:

Thank you martin_helm]( for your immediate response. Finally it seems that the g77 gcc version 3.3.5 worked out fine!

Thanx for the response
