Hi Naoto,
You are correct that I made some typos in my post and absolutely correctly described the typos. Sorry.
You, also, correctly described what happens when the cMask value has "A" as the first character.
Do I understand that in order for me to transfer the numbers "67849" and the mast "A XXXXXXXXX" into "A 67849" I need to do away with using "@R " and have a different approach? Like parsing the cMask?
