Is it possible to have a single MUMPS variable representing all subscripts for a global? For example, if I have an ^ABC global and the ^ABC(1,2) node exist, is it possible to have a variable TEMP so that ^ABC(TEMP) would represent ^ABC(1,2)? TEMP="1,2" obviously does not work since it is interpreted as a single subscript, not two subscripts.

Sure, use indirection:

>s ^ABC(1,2)=3
>s TEMP = "^ABC(1,2)"
>w @TEMP
3

You can do $Name for the global and use your subscript runtime

set gbl= $NA(^ABC)
write @gbl@(1,2)
set sub=1 
write @gbl@(sub)

I was so focused on subscripts that I forgot about indirection :-) . Thanks!

Yet another example:

USER>s ^abc(1,2)=3

USER>s temp="1,2"

USER>w @("^abc("_temp_")")
3

;; Three subscripts referencing an undefined ^abc entry
USER>set temp3 = "1,2,3"

USER>w @("^abc("_temp3_")")

W @("^abc("_temp3_")")
^
<UNDEFINED> ^abc(1,2,3)
