st: macro list limits strpos

[Jakob Petersen <jpeterb@essex.ac.uk>]

Statalist,

Problem: The following does not scale up to longer macro lists and 
variables at the end of longer macros are cut off.

***************************************************
sysuse auto,clear
findname,type(string) local(vstr)
findname,type(int) local(vint)
findname,local(vother)
local vother : list vother - vstr
local vother : list vother - vint
di "`vstr'"
di "`vint'"
di "`vother'"
foreach v of varlist * {
if strpos("`vstr'","`v'") {
di "`v' is a string variable"
}
if strpos("`vint'","`v'") {
di "`v' is an integer variable"
}
if strpos("`vother'","`v'") {
di "`v' is not string nor integer variable"
}
}
***************************************************

Any ideas?
Similar to: http://www.stata.com/statalist/archive/2008-01/msg00945.html

Tried increasing maxvar to no avail - is there away of increasing mem 
allocation here or is a different approach to -strpos- required?

Thanks,
Jakob Petersen
