Apple IIgs #43
Undocumented Feature of CalcMenuSize

Revised by Matt Deatherage (March 1991)
Written by Dan Oliver (November 1988)

This Technical Note documents that CalcMenuSize can accept a parameter of $FFFF to recalculate menus with uninitialized heights and widths.

Changes since November 1988: This Note is now obsolete.

This Note formerly described how CalcMenuSize behaves when menu widths and heights are stored as $0000 or $FFFF. This behavior is now documented in Volume 3 of the Apple IIgs Toolbox Reference on page 37-3.
