calcul in obs

Hi,

I try to do something very easy:

I have a global variable c and a SAS table A.

This is working:

data WORK.B;
set WORK.A (firstobs= 2 obs= &c.);
run;

This is not...

data WORK.B;
set WORK.A (firstobs= 2 obs= &c.-1);
run;

Isn't it possible to do it without creating another new variable??

Thanks for reply

Use

set WORK.A (firstobs= 2 obs=%eval(&c.-1));

This lets the macro processor do the calculation and hands a simple number over to the dataset option.

Thanks Kurt, it is indeed working. Have a good day
