Hello Alana,
Could you please give an example on this format usage? What I noticed is that the first range definition includes 0:
[pre]
-100000000 - 0.0001 = 'red';
[/pre]
To exclude 0 it should be changed to
[pre]
-100000000 - -0.0001 = 'red';
[/pre]
So the final format definition I think should be like this:
[pre]
proc format;
value difffmt
-100000000 - -0.0001 = 'red';
picture NegDol (multilabel)
-100000000 - -0.00001 = '000,000,000,000)' (prefix='($')
0 - 100000000000 = '000,000,000,000' (prefix='$');
run;
[/pre]
Sincerely,
SPR
