By the way, the issue is not shortness or length of memory. Stata will remember the locals indefinitely in a session that never stops, so long as they are not destroyed or overwritten. 

The issue is that "locals" are precisely that, locals within a program space: an interactive session, a do-file, do-file editor contents, and any and all spaces within which a -program- is working are all quite separate spaces.

Short answer is No. 

You need either globals or to map from one set of locals in one space to another set in another space. 

The latter can be done but is best avoided until you understand this point.

Hi all,

The syntax below works fine if I highlite all rows and click on run". Is
this what is called "a Stata session"? However, immediately after that,
Stata forgets the content of the local macros. Is it possible to make the
the local macros functioning until I close down Stata. 


local mynames   "Stockholm  Uppsala  Södermanland  Kronoberg"

token `mynames'					

local mycount: word count `mynames'		

forv i=1/`mycount' {

      local lannr = `i' + 21
      di " "
      di " "
	di in r "``i''"
