DO IF problem

[Tereshchenko, Bogdan]

Dear all,
 
I am having trouble with a DO IF command. It gives me an error message that
it is not recognized and that I should use level of control etc. I don't
know where this level of control is, and it's odd that a simple statement
that used to work no longer does:
 
namely,
 
DO IF tempcode.1=102.

COMPUTE uinccode=15.

END IF.

EXECUTE.

 

Instead, every uinccode becomes 15 (without the subsetting).

 

Thanks so much,

Bogdan

remove the dot in tempcode and replace with _
see if it works

Can also be written as :

IF (tempcode_1=102) uinccode=15 .

(Wryly) That's because SPSS does refer to a level of control indicator
in the margins, but it hasn't seemed to exist for a long time.

You've heard "remove the dot in tempcode and replace with _". That's
likely not the right advice. At least, 'tempcode.1' is a valid variable
name(*). If it's the one you want, using another name won't help.

However, make sure that 'tempcode.1' exists and is numeric. If either
is not true, you'll get pretty much what you're seeing.

It that doesn't solve it, could you post the listing, with the syntax
and the exact error message?

With 'tempcode.1' numeric in the file, the *exact* code you posted
works for me (SPSS 15 draft output; WRR:not saved separately):

DATA LIST FREE /tempcode.1.
BEGIN DATA
100 101 102 103 104.
END DATA.

DO IF tempcode.1=102.

COMPUTE uinccode=15.

END IF.

LIST.

Thank you all.

I used the advice from Manmit just in case. But Richard is right: the
problem was that a prior comment statement ended in ." (using proper
English syntax) rather than .". using SPSS-intelligible comment syntax. I
changed all comments accordingly which seemed to take care of the problem.

Thanks so much!
