st: RE: -foreach-, local macro, -split- command
String variables can not include more than 244 characters. Period.
Beyond that, I really don't get a clear picture of the precise problem.
I'd recommend
1. Take a step back. Talk about the problem and the goal.
2. Show some example data.
3. Where you are now within your coding is less important.

I have a minor problem working with a local macro created within a
loop command (-forv-), which is followed by another loop command
(-foreach-). This is the deal:
1. I lead with a -levelsof- command, then store the values in a local
macro.
2. I call the local macro in a -foreach- command, replacing a
previously generated variable with the values therein.
3. My values are actually strings and take up a bit of space within
the one variable created for them (Stata only allows up to 244
characters for string variables). This means that some of the values
don't get recorded.
4. The -split- command works wonderfully at creating a different
variables for the multiple responses recorded into the single variable
filled from my local macro.
My question is this: Is there some way I can call the values in my
local macro and record them into different variables without having to
fill the limited space Stata allows in a variable?
I guess this would be a one-to-many split, but without a variable to
actually split. The information for splitting would be stored in
another form or something.
If I have 5000 students who have each scored differently on IQ scales
at several times over several years and their position in the
distribution are stored as strings (mentally retarded, borderline, low
normal, etc.), some of the observations will, when called in the
-foreach- command, exceed the 244 character limit.
This is sort of what I'm doing:
levelsof wais, local(lev)
foreach l of lev {
replace generatedvar="`l' "...
}
split generatedvar
Everything else works fine; I'm just missing those values (strings and
portions thereof) in excess of 244 characters.
