Yeah, but wouldn't it be nice it if was? :)

Think if SomeAlpha, SomeNumber and SomeTime are null capable and the null
indicators set to *on.

Wouldn't it be nicer to see:

Eval        SomeAlpha = 'something'
Eval        SomeNumber = 10
Time        SomeTime
Update    SomeRecord

instead of:

Eval        %NullInd(SomeAlpha) = *off
Eval        SomeAlpha = 'something'
Eval        %NullInd(SomeNumber) = *off
Eval        SomeNumber = 10
Eval        %NullInd(SomeTime) = *off
Time        SomeTime
Update    SomeRecord

What do you think?
