Support.sas.com states the following:

@n
moves the pointer to column n.

Range: a positive integer
Tip: If n is not an integer, SAS truncates the decimal value and uses only the integer value. If n is zero or negative, the pointer moves to column 1.

But when I tried the following code a syntax error appears:
data test;
infile tests obs=5;
input ID $ Name & $14. @-27 (a1-a5) (3.) Level $;
input ID $ Name & $14. @-27 (a1-a5) (3.) Level $;
run;

When I replaced -27 with 27.78 then also the syntax error appeared. Finally when I replaced 27.78 with 27 the program worked fine. Can someone explain that why is the Tip on support.sas.com not working? I'm using SAS 9.2.

Again, which tip.

If is an expression, the operation works as described. I does fail as you described when you provide a literal.

The problem is that the compiler can't differentiate between, for instance, a subtraction and an infix operator because the context is not clear.

There is a pretty full discussion at
