Greetings!

I want to fix User Parameters using LT.
For this purpose, I want to loop over visible User Parameters.
To do this I need to get the total number of defined items.

How do I get User Parameter count?

Thanks.

Great idea!
Looking forward to testing this.

There is no difference on how they work. Loop command was introduced first to cover the most typical use of a loop and for command was added later to be like C language.

OK, thank you for clarifying this.

I had another side question.
https://www.originlab.com/doc/LabTalk/guide/Looping-Over-objs provides many examples using both for and loop LT commands.
What are the principal differences between for and loop commands?

And to find the count, try

Got it!
Thanks.

I tried using the following snippet:
for(int j = 1; j <= 10; j++)
  {
   type wks.UserParam$(j)$;
  }

However, when j equals from 1 to 3 it returns units of the columns.
This seems to be odd since UserParam should return parameter names.
