pop up messenge for label

[Joel_112]

I have created a caption label with 5 lines that works well for me, most of the time. Some times I misjudge the size of the line and the last letter is cut off the label.

I am using Avery 5160 label, each line is in Arial 8 point type, 42 spaces seems to be the max.

I would like the write a script, with a pop up messenge telling me I have reached 42 spaces and stop typing on that line. This script would repeate itself for each of the line. line1, line2, line3, line4, line5
