Re: Generating an index, but forcing it to start at a particular point

[Sibusiso Moyo]

Dear all,

To generate an index count from 1 to whatever one can use:

Compute index = $casenum.

But what if I want to start at say -20 to -2?

Any ideas?

There's always simple addition:

COMPUTE INDEX  = $casenum - 21.

If you want your first index value to be #START, say -20, and your
increment to be #BY, say -2, you can write

COMPUTE #START = -20.
COMPUTE #BY    = -2.

COMPUTE INDEX = #START + #BY($CASENUM-1).

However, since this IS simple, I'm probably misunderstanding you ...

COMPUTE index = $CASENUM - 20 .


HTH,
