Hi marco, to make it work, you may either you put the whole statement in a string or use "Symbol": For[i=1,i<3,i++,ToExpression["q["<>ToString[i]<>"]=0;"]] or more elegant For[i=1,i<3,i++,Symbol["q"][i]=0] hope this helps, Daniel Marco Gabiccini wrote: > Hi all, > > I would like to do something like: > > For[ i=1, i<n, i++, ToExpression[ "q" <> ToString[i] ] = 0 ] > > that is assigning q1=0, q2=0, etc... but it does not work. > > I would not like to use the easy way out: > > For[ i=1, i<n, i++, q[i] = 0 ] > > of employing q[i] instead of qi. > > Can you help me please? > > Thanks, > > Marco > > Ing.
