If you tokenize into two or more macros, you lose any spaces between them. If you put them back together without spaces, as I understood you to recommend earlier, and as is recorded in your posting, you may run them together: 

. tokenize "frog toad"

. di "`1'`2'"
frogtoad

In the context of this thread, you may run together a subcommand and some other stuff, thus creating garbage. Thus "regress other stuff" is likely to become 

regressother stuff

I use -tokenize- here, but as said the point is wider.

Hi, Nick,

I am not sure what can be good about it. A space that separated subcmd
from the rest remains with the rest anyways and adding another will
double it:
local 0 `"foo "bar""'

. gettoken subcmd 0: 0

. di `"[`0']"'
[ "bar"]

. local 0 `subcmd' `0'

. di `"[`0']"'
[foo  "bar"]

Regards, Sergiy
