AKazak	Posted - 02/19/2021 : 10:43:52 AM 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. --- Andrey

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

Thank you for the suggestion. As for 0 and <end>: Do both act in the same way? Can I use any? --- Andrey
