You have to be a bit careful not to evaluate the local
containing such a long string (i.e. avoid using the "=" when
defining a local), but otherwise there should not be a
problem with -gettoken- or the extended macro functions (I
always type -help macro- and follow the link to the helpfile
for the extended macro functions), even if the local surpasses
the 244 tokens limit. This is illustrated in the example
below:
*------------ begin example -------------------
forvalues i = 1/60 {
local lstring "`lstring' very"
}
local lstring "`lstring' long string"
// the string has more than 244 characters:
di `: length local lstring'
// -gettoken- works:
gettoken first rest : lstring
di `:length local first'
di `:length local rest'
*------------- end example --------------------

Hope this helps,
