st: problem with -mat_capp- command

["Zurab Sajaia" <zsajaia@hotmail.com>]

Dear all,

Although -mat_capp- is undocumented command and "is of very limited 
interest, usually only to Stata programmers ..."  I decided to post this 
question, in case folks at Stata have plans to update it.

when merging matrices containing spaces in column names -mat_capp- was 
issuing the "conformability error

.matrix a= 1,2
.matrix colnames a="one two" three
.matrix b=1\2\3
.mat_capp c : a b, miss(.z)


problem seems to come from the line:
mat colnames `bb12' = `:colfullnames `b1'' `:colfullnames `b2''

and possible solution could be
mat colnames `bb12' = `:colfullnames `b1', quoted' `:colfullnames `b2', 
quoted'

(from reading the help, I was under impression that option 'quoted' was 
for -coleq-, roweq- only but it seems doing the same thing 
with -colfullnames- as well)

I'm using -mat_capp- in my program that is distributed to other users so now 
I'm deciding whether I wait for the next Stata update or consider other 
solutions in my code?
Thanks for any advice,
Zurab
