unab vmacro: abc*
global varmacro "`vmacro'"

note: do not use the equal sign when creating string macros, it can truncate the result

Hi All,

I'm trying to create a global macro containing certain variable names - but I'm having trouble appending/concatenating macros (as opposed to redefining the macro).

Assuming I have some variables called abc1, abc2, and abc3, here's my do-file so far:

foreach var of varlist abc* {
global varmacro = `"`$varmacro' `var'"'
}

This currently only stores (in varmacro) the last abc* variable ("abc3"), whereas I want it to produce a macro of "abc1 abc2 abc3".

I would have though this command could be done in one line rather than using a do-file, but would appreciate any method that works.

Thanks in advance,
Dave
