You have to provide a valid expression as a parameter

ccolval = evaluate('mycursor.COL' + TRANSFORM(i))

>I need help to understand the 'Evaluate' function.
>
>Please try run the following example:
>

create cursor mycursor (id i,col1 c(3),col2 c(3),col3 c(3))
>insert into mycursor (id,col1,col2,col3) values(1,'AA','BB','CC')
>insert into mycursor (id,col1,col2,col3) values(2,'EE','FF','GG')
>
>select mycursor
>scan
>	for I=1 to 3
>		ccolval=evaluate(mycursor+'.COL+str(i)')
>		messagebox(ccolval)
>	endfor
>endscan
