Hi all,
Hopefully I'm not going crazy, but I could have sworn in UD 7.1 that
doing a <-1> to append an empty string would not actually appended
anything. For example:
As I understood it, the problem was always appending TO an empty string,
not appending an empty string (though I was always used to INFORMATION
:-)
Because an empty string could have no values, or 1 empty value, PI
always assumed it had no values. So ...
VAR = ""
VAR<-1> = ""
VAR<-1> = "A"
would leave VAR equal to A
But a further
VAR<-1> = ""
would then append a null to give "A":@FM
All very logical (as I would expect from Prime :-)
Cheers,
Wol
