#49670 - 10/09/14 08:20 PM adding a column
FormMaster OL Expert Registered: 05/12/03 Posts: 193 Loc: Los Angeles	Hi, Believe it or not, I have been working on forms for 8 years and have NEVER had to add (sum) a column of numbers. What is the easiest way to do this? I have a column of numbers that runs from line 23 to 33, and within columns 4-6. Thank you.

FormMaster OL Expert Registered: 05/12/03 Posts: 193 Loc: Los Angeles	Hmmm. I tried this, but I get a "string too long" error. Edited by FormMaster (10/10/14 10:14 AM)

Add &current.line := &current.line + 1 in the loop. Like this: Code: Define(&total, integer, 0) &current.line:= 23 Repeat() &total:= &total + strtoint(@(&current.line,4,6)) &current.line := &current.line + 1 Until(&current.line = 33) Show(inttostr(&total)) Given that you have specified line range, I would probably use a For loop here... Code: Define(&total, integer, 0) for(&current.line, 23, 1, 33) &total:= &total + strtoint(@(&current.line,4,6)) endfor() Show(inttostr(&total)) For loops automatically increment the control variable so remove the susceptibility to forget it.

FormMaster OL Expert Registered: 05/12/03 Posts: 193 Loc: Los Angeles	James, This works correctly except it is only picking up the 3 digit numbers. We're watching columns 4-6, but the data might be 1, 2, or 3 digits long - like this: ..2 ..5 .10 105 ..4 115 (the dots are empty space) So right now, it's giving me a total of 220. it's only seeing the 3 digit numbers. How do we make PP see all the numbers? Thanks. Edited by FormMaster (10/10/14 11:03 AM)

jim3108 OL Expert Registered: 04/19/10 Posts: 316 Loc: London, UK	OK. If the dots are empty space it should convert to the integer correctly. If they were dots it would need to be: Code: Define(&total, integer, 0) for(&current.line, 23, 1, 33) &total:= &total + strtoint(strip('.',@(&current.line,4,6))) endfor() Show(inttostr(&total)) Try trimming the selection before we convert: Code: Define(&total, integer, 0) for(&current.line, 23, 1, 33) &total:= &total + strtoint(trim(@(&current.line,4,6))) endfor() Show(inttostr(&total)) Is it at all possible that there is another character in the empty spaces?

jim3108 OL Expert Registered: 04/19/10 Posts: 316 Loc: London, UK	I have just tested this and it works. That is not to say that you aren't still having problems so let's look a little closer. Can you send me your data file? Edited by jim3108 (10/10/14 11:35 AM) Edit Reason: Why do I need a reason?

FormMaster OL Expert Registered: 05/12/03 Posts: 193 Loc: Los Angeles	This is the strangest thing. I'm not getting any compile errors, but the box on the form is simply blank. Not even a zero. Am I missing something? Do I need to do anything else beside create a PP object and place it on the form with the above code? Yes. I will send the data file. Thank you.

jim3108 OL Expert Registered: 04/19/10 Posts: 316 Loc: London, UK	Ok let's go from the start. Simple document * Sample data - ASCII (or Line Printer) * Page 1 - Normal Page -> on page 1, place PressTalk object. -> in PT object, paste my last code example. What do we get on page? PS: We are working with ASCII text here aren't we?
