Kirk, first of all, I apologise and thank you for your patience! It's because my English is bad.
The {wdat} variable outputs the full date, all correct.
I was trying to understand why the names of the months April and March are not abbreviated when I use variables {wdat}, {imap} and {mnap}. I thought the result of these variables would look like Apr. and Mar., not April and March. I was confused by the fact that not all month names are abbreviated as written in the description of the variable {mnap}: Capture month name abbreviated for AP (Jan., Feb., etc). I looked at the table of abbreviations for month names and saw that only May, June and July are not abbreviated. That's what baffled me.
PS Thank you for the great software, you saved me tons of time!
Спасибо!
