This I did not know. Thank you.

This I did know. As I said in my initial message:

I realize that I could use: 'set the dgProp["column widths"] of grp <DG> 
to <returnDelimitedListOfWidths>' as a single set action vs a loop where 
I am using 'set the dgColumnWidth[tColumnName] of grp <DG> to 

However, there are only Datagid properties so set attributes for ALL 
columns for alignments, visibility, widths, and labels. Therefore, I 
have to use a loop anyway to set the tooltip, sorttype, sortdirection, 
end editability

SO, while I can change the code to set the column ALIGNMENTS and WIDTHS 
all at once, I am still stuck setting the TOOLTIP, SORTTYPE, 
SORTDIRECTION, and EDITABILITY column by column in a repeat loop. So 
what do I do about setting the TOOLTIPs? There is NO 'set the 
dgProp["column tooltips"] of grp <DG> to <returnDelimitedListOfTips>'

Obviously, I can just TRY using LOCK MESSAGES (as Paul Hibbert 
suggested), but I am concerned that may cause more problems that it 
solves. Does anyone KNOW for sure?
