G0025 : Undefined symbol: 'graphset'

graphset is part of the PQG library. You need to add the following statement to the top of your program.

library pgraph;

G0025 : Undefined symbol: 'graphset'

Thanks very much. Actually, the error comes with adding library pgraph;

These are the whole codes:

Another question, What do (load res and load ax) mean?

Thanks in advance ..

1. What happens if you enter these two commands at the GAUSS command prompt?

   library pgraph;
   graphset;

2. load ax means: load data from the file ax.fmt located in your GAUSS working directory into a GAUSS matrix named ax.

1- when I run the above codes 2 errors  appear  (G0025 : Undefined symbol: 'graphset') and  (G0008 : Syntax error '#include maxlik.ext')

If you entered these two separate commands

library pgraph;
graphset;

one after the other at the GAUSS command line, it is quite strange to get these two errors:

(G0025 : Undefined symbol: 'graphset') and  (G0008 : Syntax error '#include maxlik.ext')

It seems likely that either many of your GAUSS installation files have been modified, or you highlighted a larger section of text and selected 'run selected text'.

Which version of GAUSS are you using?
