Extracting discreet values from multiple value parameters 2

[Davest11]

I'm using CR v10, SP 3. Is there a way to extract the individual values from a multiple value parameter? For instance, I have a string parameter that allows the user to enter either multiple discreet values or range values. Is there a way in which I can check how many characters are in the first entry? If I use

length (<parameter>)

I get the "string required" error message, because the parameter is actually an array. I tried using a subscript, but that doesn't work at all (ok, I *knew* it wouldn't be that easy).

Thanks,

If you wanted to display all selected parameter values, you would use a formula like:

whileprintingrecords;
string range array parm := {?rangeorindivparm};
numbervar i;
numbervar j := ubound(parm);
stringvar display;

for i := 1 to j do(
display := display +
if minimum(parm) = maximum(parm) then
minimum(parm) else
minimum(parm) + " to " + maximum(parm) + ", "
);
left(display,len(display)-2);

Not sure if this is why you were asking, but you could adapt this to other purposes.

Thanks, LB - this is axactly what I was looking for. I knew that the parameter was actually an array, but I couldn't come up with a way in which I could interact with it as you can with an array variable. It didn't cross my mind to try to apply the parameter to an array variable and then manipulate the variable.

Thanks,
