## Re: Proc Format

Depends on what you mean by correct. It'll work but does it give you what you want.

You need to check it with either your data or some test data to see if it's what you want.

Here's a way to test it with sample data, notice the boundary value tests and then the negative numbers:

data test;

format a 20.8;

input a;

cards;

-2.345

3.2342

5.2381

5.2382

5.2382134

5.23825

5.2382767

5.2833

5.2833124

5.28335

5.28335789

5.2834

5.3432

6.2343

;

run;

proc format;

value graftsfmt

0-<5.2832="<25th Percentile"

5.2833-high=">=25th Percentile"

;

data want;

set test;

b=a;

format b graftsfmt.;

run;

proc freq data=want;

table a*b/missing;

run;

## Re: Proc Format

You are currently making a STRING format, Change the value statement to: value graftsfmt

to allow use with numeric variables.

## Re: Proc Format

Thanks for the reply....Other than that do you think this is also correct?

proc format;

value graftsfmt

0-<5.2832="<25th Percentile"

5.2833-high=">=25th Percentile"

;

Also, I suggest setting the FUZZ to zero.

value graftsfmt (fuzz=0)
