The macros would become quite complex if you had to check every command before you use them.
But maybe some sort of error handling would be useful.
Perhaps something like ON ERROR on Basic.
Currently, you could simply check the version number.
In order to be able to say "version x.y is required", you would need to know which version is required anyway.
Of course we need a list of versions on which each command was introduced. You could check
but that is not complete. For example, the command Reg_Prep is not mentioned.
(By the way, the commands Date_Day, Date_Month, Date_Year are listed as new commands both for version 6.20.1 and 6.15.4.)
(And version 6.20.2 is not mentioned at all.)
