The LineInfo must have been created with forPaint: TRUE.Finds the character pointed to.Finds the position of the indicated character.  Returns FIRST[INTEGER] or LAST[INTEGER] if the character occurs before or after the line, respectively.This is how to get working space. Keeps a small cache of storage.A promise that the client is done with this LineInfo. Use whenever possible to save on allocations.Michael Plass, February 1, 1983 9:15 am: conversion to UnifiedFontsMichael Plass, August 9, 1983 2:23 pm: conversion to Imager‌ت-  ک Jڑœ@™@Jڑœ,™,Jڑœ)™)unitڑدk	ک	Jڑœ‌œ‌œکJڑœ
