Does label1 hold the correct value?   Since I don't see any thing
obviously wrong with the fscanf statement I am going to assume that
label1 is a string variable holding the correct label.  Then your code
would look something like this:

label1 = fscanf(fp0,"%s","C");
cmd = fprintf("gset label %s at .8,.2",label1);
eval(cmd)

You could also do something very similar with the graw command. 
However, I prefer the above method.  Octave does not interpret variables
on a line starting with gset.  If it did it would try to interpret the
"label" and "at" which would most likely lead to an error.
