Re: st: workaround for macro length problem with levelsof() ?

[Keith Dear <keith.dear@anu.edu.au>]

Dan,
Instead of
        local filepath = "c:/mydata/`name'"
try simply
        local filepath c:/mydata/`name'

The point is that the = unnecessarily evaluates 
the subsequent expression as a string, before 
assigning it to the local macro, and strings are 
indeed limited to 244 characters (this has come 
up here several times recently).

Also instead of -clear-, -drop _all- may be 
enough. I don't know if it matters here.
