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.

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.

Try

loop(i,1,10){wks.userparam$(i)=;};


And to find the count, try

nn=0;loop(i,1,10) {if(wks.userparam$(i)) nn = i;};nn=;

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?

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.

We added wks.UPC (user parameter count) for 2022, so it can be

loop(i,1,wks.upc) {wks.userparam$(i)$=;};
