Proc format error

[Ronein]

Hello

Why this proc format has a problem?

I want that 350000 has a separate group.

I  want that between 300000 (not included) and 350000 (not included) has a separate group too.

The error is:

162 300000<350000='(8) 300-350'
______
22
76

proc format;
value FFF
0="(1) 0"
0<-50000='(2) 0-50'
50000<-100000='(3) 50-100'
100000<-150000='(4) 100-150'
150000<-200000='(5) 150-200'
200000<-250000='(6) 200-250'
250000<-300000='(7) 250-300'
300000<350000='(8) 300-350'
350000='(9) 350000'
;
Run;

You always need a hyphen in the range. The angled bracket is used to exclude the edge value. To exclude both edges, use

300000<-<350000='(8) 300-350'
