Subject: Re: How to reverse variables
Jonathan, Max and Paul -
I tried the following and it still does not work as proposed by what was
posted on SAS-l.
%let n = 5;
The output is:
OBS V1 V2 V3 V4 V5
1 2 1 3 4 5
on OpenVMS SAS version 6.12 running TS065
I suspect there is a problem but not sure where to look.
I really do not have time to research this as it is only a tip and not a
real problem for me to find an answer to.
