Hi
Jason,
Although it
references some different error numbers, I believe resolution 80373 provides the
answer:
While a
blank is the "most common" token delimiter, it's not the only one. Minus
signs, among other things, are defined as tokens in and of themselves. So
this:
-6
Even with no
space in between them would be read as two separate tokens: - and
6.
So the only
way to submit a negative number as a token parameter is to use something other
than !Positional -- !ENCLOSE, for example:
define vars4
(!pos !enc('<','>')/!pos !enc('<','>')/!pos !enc('<','>')/!pos
!enc('<','>')).
compute
int=!1.
compute bt=!2.
compute bbde=!3.
compute
btxbde=!4.
!enddefine.
vars4
<96> <-.76> <-5.4> <1.9>.
exe.
Or you could use !CHAREND:
define vars4 (!pos
!charend('/')
/!pos
!charend('/')
/!pos
!charend('/')
/!pos !charend('/')).
compute int=!1.
compute
bt=!2.
compute bbde=!3.
compute
btxbde=!4.
!enddefine.
vars4 96/ -.76/ -5.4/
1.9/.
exe.
Or. you can still use !POS if you quote
the token. But then you have to !UNQUOTE the token in the macro
definition:
define vars4 (!pos !tok(1)/!pos !tok(1)/!pos
!tok(1)/!pos !tok(1)).
compute int=!UNQUOTE(!1).
compute
bt=!UNQUOTE(!2).
compute bbde=!UNQUOTE(!3).
compute
btxbde=!UNQUOTE(!4).
!enddefine.
vars4 '96' '-.76'
'-5.4' '1.9'.
That works as well.

I have been working with macros for some time but just ran into a
bug.
I have written a macro that generates data from a population with specific
parameters. One parameter is a correlation I introduce between two variables. I
specify weights for combining two random variables to form a new variable.
Program runs fine unless I specify the weight as a negative value.
The issue seems to be that the negative value is not being passed from the
macro call line into the macro.
..not sure if this is unique to v 17 because in all my prior work I have
never tried this.
Has anyone had similar problem? If so, can you recommend a solution?
