I have a program written in Lattice 3.10 'C' which I compiled and linked
just last night, it runs IntuiTextLength just fine. I fear that it must be
the Modula interface library. The following is taken by MetaScope from my
program, and is the listing of the Lattice _IntuiTextLength interface
routine (argument apparently pushed onto stack just before JSR to here).
