How do I create a format for there ranges? > Why does SAS think these ranges overlap?

[mohassan99]

   proc format;
      value  $PRV_ID 	        'H0000000' - 'H9999999' = 'Hospital'
						'A0000000' - 'A9999999' = 'A...'
						'P0000000' - 'P9999999' = 'P...'
						'Q0000000' - 'Q9999999' = 'Q...'
						'1000000000' - '1999999999' = 'NPI'
						'000000001' -  '999999999'  = 'TIN'
             			                Other='?';
   run;

Log:

24 proc format;
25 value $PRV_ID 'H0000000' - 'H9999999' = 'Hospital'
26 'A0000000' - 'A9999999' = 'A...'
27 'P0000000' - 'P9999999' = 'P...'
28 'Q0000000' - 'Q9999999' = 'Q...'
29 '1000000000' - '1999999999' = 'NPI'
30 '000000001' - '999999999' = 'TIN'
31 Other='?';
ERROR: These two ranges overlap: 000000001-999999999 and 1000000000-1999999999 (fuzz=0).
NOTE: The previous statement has been deleted.
32 run;

Because you are formatting a character variable, SAS will use lexicographic ordering  (i.e. like in a dictionary, comparing first characters, then second characters, etc).  Therefore you can have, where the outer values are 'NPI' and the middle value is 'TIN'.

   '000000001'   < '1000000000' < '1999999999'

Now if the TIN values another leading zero, you could use:

proc format;
      value  $PRV_ID 	        'H0000000' - 'H9999999' = 'Hospital'
						'A0000000' - 'A9999999' = 'A...'
						'P0000000' - 'P9999999' = 'P...'
						'Q0000000' - 'Q9999999' = 'Q...'
						'1000000000' - '1999999999' = 'NPI'
						'0000000001' - '0999999999'  = 'TIN'
             			                Other='?';
   run;

would work.

If your actual values for TIN are 9-characters, instead of 10 as I use in the value statement, you could catch and modify those X values, and then successfully use this format.

You may want to double check the logic of the format in general. Ranges of character values often do not behave as expected.

Example:

proc format library=work;
      value  $PRV_ID
'H0000000' - 'H9999999' = 'Hospital'
'A0000000' - 'A9999999' = 'A...'
'P0000000' - 'P9999999' = 'P...'
'Q0000000' - 'Q9999999' = 'Q...'
'1000000000' - '1999999999' = 'NPI'
/*'000000001' -  '999999999'  = 'TIN'*/
Other='?';
run;

data junk;
x='H0A';
put x $prv_id.;
run;

Has this result:

39
40   data junk;
41   x='H0A';
42   put x $prv_id.;
43   run;

Hospital

Do you want a value of H0A to have the formatted value of Hospital?

This may be one of those times that you need to generate a data set with the explicit known values and use them to create a CNTLIN dataset.
