OriginPro 2021b (64-bit) Beta 6 9.8.5.111
Windows 7 Pro x64 SP1

Greetings!

A simple, but important question: how does one put a variable numeric value to X-Function argument?

For example, this piece of code doesn't work:
plot_gboxindexed -r 1 irng:=[%(page.name$)]"%(wks.name$)"!3:%(wks.nCols)


How do I put the value of wks.nCols after the colon?

Thank you.

% convert string expression to a string, so you should use $ to convert a numeric expression to a string, so try 

plot_gboxindexed -r 1 irng:=[%(page.name$)]"%(wks.name$)"!3:$(wks.nCols)


better yet, use 0 as end


plot_gboxindexed -r 1 irng:=[%(page.name$)]"%(wks.name$)"!3:0


0 as end was not as fully implemented before 2021b, so might need to use <end>

You can read more about % and $ here

I will study more about % and $ @ https://www.originlab.com/doc/LabTalk/guide/Substitution-Notation.
Thank you for the suggestion.

As for 0 and <end>: Do both act in the same way? Can I use any?

0 was not generally implemented before, but in 2021b we try to cover all cases to allow 0, like 

wcol(0)=col(A)
and in such case <end> cannot be used. <end> was only supported in range notation and in 2021b, 0 will work the same as <end> for range, but 0 can also be used like

layer -d 0
to delete the last sheet.

Thank you.
Very handy syntax and I will be using it in my code.
