I want to use proc format on the values below. Example: 1.0-1.9 is 'Pre-functional'. I have to format them as character due to other values such as P1,P2, etc.
will this work?
proc format;
value $ engproffmt
'1.0 - < 1.9' = 'Pre-functional';
1.0-1.9 |
2.0-2.9 |
3.0-3.9 |
4.0-4.9 |
5.0-5.9 |
6.0 |
P1 |
P2 |
P3 |
P4 |
8 |
9 |
W |
X |
You may want to run this code and see if the formatted values match what you would expect with your data.
Normally in a numeric format the -< means "up to but not including" so 1.9999 would be "pre-functional" and 2 would be "something else". Note that characters use the active sort sequence (ASCII or EBCDIC depending on environment) and does a character-by-character left-to-right comparison for range membership. Some things may not quite what you expect such as values of 1 and 2 (note no decimal present)
proc format library=work; value $ engproffmt '1.0' -< '2.0' = 'Pre-functional' '2.0' -< '2.9' = 'Something else' '3.0' -< '3.9' = 'YadaYada' ; run; data example; input x $;
/* so you can see the unformatted value
in proc print below*/
y=x; datalines; 1.0 1.01 1.1 1 1.A 10 1.9 1.90 1.93 2 2. 2.0 ; run; proc print data=example; format x $engproffmt.; run;
Explicit values may be better if known.
Programming ranges within a character format is tricky and prone to error. As a general rule, avoid it whenever possible. For this limited case, you could use:
value $engproffmt
'1.0' - '1.9' = 'Pre-functional'
'2.0' - '2.9' = 'Next level description';
I do not believe what you have will work with the sample data you have provided.
You may have to list each stringed value.
here is a nice link to formatting.
