During my last migration to IRIS I met this Compatibility parameter
- NullSubscripts true
0 - Throw error when referencing a null subscript. 1 - Null subscript references do not throw an error.
The consequences are shocking. This was allowed:
USER>zw ^rcc
^rcc=0
^rcc("")="***"
^rcc("",1)="*,1"
^rcc(1,"")="1,*"
^rcc(1,2)="1,2"
^rcc(1,2,"")="1,2,*"But SMP had no idea what is going on. .png)
And after switching off that flag this was still partialy visible, but read-only
USER>zw ^rcc
^rcc=0
^rcc(1,"")="1,*"
^rcc(1,2)="1,2"
^rcc(1,2,"")="1,2,*"I just don't understand.
