Apple does not support any Toolbox routine that is not a built-in Macintosh
Pascal function or procedure documented in either the Reference Manual or
the Technical Appendix. We can only refer you to the Inside Macintosh
documentation. A brief description of "Inline", a routine which enables you
to access the Toolbox, may be found on the Macintosh Pascal diskette in the
text file named "InLines". Note: careless or erroneous use of the "InLine"
facility can be fatal to your diskettes or data.
