Why so output is like this ?

Attyslogin — Sun, 26 Jun 2016 06:47:14 GMT

Raw File :

---------10---------20---------30

72 95

SAS Program :

data test;

infile "Rawfile";

input @1 height 2. @4 weight 2;

run;

why weight variable is taking a value specified to next to it (only single digit) instead of 95 from raw file.

Output is :
_____________
Height Weight

--------------------

95 2

Your missing a period at the end of your second format.

If you exclude formats and @ position SAS will most likely read it correctly by default.

@Reeza, yet the "2" didn't generate an error. How is it interpreted?

It's interpreted as taking the contents of column 2. You could code:

input @4 col1 1 @4 col2 2;

The @4 is irrelevant, overridden by the later instructions. COL1 will be the contents of column 1, and COL2 the contents of column 2.

Oh yes! The old column input. The burden of legacy...
