Thanks for taking the time to work this out; this is a big help!
The problem with this is that it does add a lot to the size of my file, but
.... I got 2 gigs of memory and lots of disk space. Again, thank you ...

Subject: st: RE: RE: RE: suggestion for Stata 8: value labels for string
variables
It seems to me that the answer here is to store the "labels" in a
separate string variable. Then you can use the short name variable or
the long name variable (ie, the "value" or the "label") as you like.
This is, I think, the direction that Nick Cox is going here.
To do this, and apply it across multiple files, first create a stata
dataset with two string variables: the short "value" variable, and a
longer, "label" variable. This should have one record per label. (You
could probably read this using -infix- directly from your SAS proc
format text file.
. clear
. infix str4 cause 2-5 str80 label 9-89 using labels.txt
(13 observations read)
(You will need to play with the column positions given your SAS PROC
FORMAT file, but this gives you the idea...)
. list
cause
label
1. A391 Waterhouse Friderichsen
syndrome'
2. A483 Toxic shock
syndrome'
3. A985 Hemorrhagic fever w renal
syndrome'
4. B222 HIV dis wasting
syndrome'
5. B230 Act HIV infect

6. D469 Myelodysplastic syndrome,
unspec'
7. D593 Hemolytic uremic
syndrome'
8. D65' Diseminated intravascular coagulation [defibrination
syndrome]'
9. D762 Hemophagocytic syndrome, infect
assoc'
10. D814 Nezelofs
syndrome'
11. D820 Wiskott Aldrich
syndrome'
12. D821 Di Georges
syndrome'
13. D824 Hyperimmunoglobulin E [IgE]
syndrome'
. replace label=substr(label,1,index(label,"'")-1) if
index(label,"'")
(13 real changes made)
. replace cause=substr(cause ,1,index(cause,"'")-1) if
index(cause,"'")
(1 real change made)
This gets rid of the trailing single quote characters in each
variable...
