1.) please don't use html mail in future posts.
2.) i'm still not entirely sure what you want to do here, but from
your description it sounds as if there are several things done in
an unnecessarily complex way? Even if the include file is sacrosanct
as you say (BTW: I would never accept such a statement), you could
still treat it as a normal ASCII file and read in the variable definitions
e.g. into structures like { varname:"Joe", value:"200" } or into
two arrays: strarr() and values(). This would make searching and
matching much easier.
3.) but if you really need to include the include file as such,
Reimar Bauer can probably tell you how to use the undocumented
features of routine_name() to achieve what you want.
