Hi All
I'm not so sure how to use evalString. for example, i want to read the point numbers , a series of point numbers , like in group sop, you can specify the point numbers, 0 1 2 3 , etc.
my question is how do u parse a string and convert it to float or integer?Or to make sure that the user can enter only integer values and parse the string.
Thanks

thanx.
i'll give it a try.
