Hi there,
I've got a problem with the right adressing of multiple cols.

I can use the command in the command window
col(d) = -ln(col(c)) and everything works fine.

But if I use [bk$]$(1)!col(d)=-ln([bk$]$(1)!col(c)) I'll get an error: Math can not be used with text columns (my free translation from German).
Do you have a clue, what I'm doing wrong? I've used the e.g. [bk$]$(ii)!cell(rownr,4) for other stuff and everything was right. bk is here bk$=%H.

Thanks in advance!
Peter

Range notation is used exclusively to define range variables. It cannot be used as a general notation for data access on either side of an expression.

string bk$ = %H;
range rc = [bk$]1!col(c);
range rd = [bk$]1!col(d);
rd = -ln(rc);

Note that $(1) is redundant. You only need the 1.
