Hi,

I am abit new to SAS programming, I wanted to know what the declarations like $ and @ mean in the following piece of SAS code.

;INFILE IN1
;
; INPUT TSTM TSTD TSTY
; FILE OUT
; NOW = MDY(TSTM,TSTD,TSTY)
;
;INFILE IN2
;
;INPUT N1 1-8 N2 $10 N3 $72
; IF NOW = MDY(06,30,2000)
;PUT N1 MMDDYY4. @5 N1 YEAR4. @10 N2 @72 N3

Thanks in advance,
Kiran.

Hi Bajji,

@ indicates the starting position of the field in the file

$ indicates that it is Standard Character data

Hope you got it.

Bye
