I just wanted to run a script which worked properly around 3 months

(using current cvs at this time on Win 7).
I set up two inner loops (called LOOP and j, respectively) and have the
following command:
<hansl>
matrix b_D$LOOP_E$j_sim = zeros(n_rep,ncoff)
</hansl>
Unfortunately this is not working any more with a ten days old csv, and I
obtain the following msg:
"Varname 'b_D$LOOP_E$j_sim' contains illegal character '$'
Use only letters, digits and underscore"
Can you give us some more context? I tried the following test:
<hansl>
loop LOOP=1..2 -q
loop j=1..2 -q
matrix b_D$LOOP_E$j_sim = zeros(LOOP,j)
print b_D$LOOP_E$j_sim
endloop
endloop
</hansl>
and it ran without errors on current CVS.
