As an addendum to Howard's recommendation, make sure that the numeric variables are stored as length 8 rather than something shorter, both in the data set fed to PROC FORMAT and in your "main" data set (assuming that in real life you're not just reading in cards as in your example).

It's also worth noting the log messages in Roland's previous response. What goes into an informat is by definition always character, not numeric.

If all else fails, and assuming your original values are all between 0 and 1 with 5 decimal places, try integerizing (is that a word?) everything:

proc format; ... '81456'-<'81562' = 1001 etc.

then in your DATA step:

CBR_MEND = input(put(CBR_test*100000,z5.),mapf.);

Look into the FUZZ= option for your INVALUE statement. If that does not do it, you may have to apply the ROUND function to the boundary values in the CNTLIN= data set and/or to the CBR_MEND values.
