Your ".profile" is setting the variable TWO_TASK to a value but it's nor exporting it. After ".profile" has finished TWO_TASK will not be available anymore. So if you have to have it export it also.

A statement in ksh is finished either by the end of the line or by a ";" if you want to code more than 1 stmt on 1 line.

I my conclusion I meant you could call:
 my @envlines =  (`exec ksh -c ". .profile; ISWTEST; env"`);

This should set all vars in .profile and then change some to different values as in the specified alias "ISWTEST" and then finally grab everything as described earlier.
