Yeah, dream on

You wish to format the output of C:Date, but VERY SADLY, C:Date does not support that, so you have to jump through hoops around the problem.
Echo to T:timestamp
Makedir `List DATES T:timestamp LFORMAT %D`
Delete T:timestamp QUIET
This creates a temporary file, which you then can list with LDORMAT %D to get the date from, but you need "DATES" parameter or it will always say "Today", and then make a directory with this name - also SADLY it will be 29-Jan-20 and not 29-01-2020, and there is little you can do about that, and also this output depends on locale, so in case of the month of May, a system with English locale will for example say "29-May-20", while with Norwegian locales will say "29-Mai-20" and Swedish "29-Maj-20" etc.
If you think that this is all crazy and should be corrected, you can join my whining choir...
