Subject:      Re: Negative numbers in a PROC FORMAT value clause

Hi Jim,

I think it should work correctly without the parens. So:
VALUE eng_back low--1  = green
               -1-0    = yellow
               0-1     = red
               1-high  = black
as it is unambiguous.

More readable would be to insert spaces:
VALUE eng_back low - -1  = green
               -1 - 0    = yellow
               0 - 1     = red
               1 - high  = black

Question: how about the range limits themselves?
Might it be better to code something like:
VALUE eng_back low -< -1 = green
               -1 -< 0   = yellow
               0 -< 1    = red
               1 - high  = black

Regards - Jim.

specify negative numbers in a value clause in PROC FORMAT and don't know how

something like the following but I don't know the right syntax.
