Thank you so much!, why do you use $3 instead $4 i don't understand the $ sign, is that mean by columns? 3rd column?

Hi @Lvp8906  The instruction that is given using Input statement goes like this:

$3-  $ dollar stands for the value to be read a character. 3 bytes of character to be read from the input buffer into the PDV to the build the observation. 001 002 appears only 3 bytes with 1 byte of space for each character.

Yes one column position contains value of 1 byte

@Lvp8906  - $3. defines how SAS reads the ID data. $ means read the data as character, 3 means read the first three columns of data.
