Chapter 6 - Script Manager / Script Manager Reference

Routines

The Script Manager routines documented in this section allow you to

• control the system direction
• access Script Manager variables
• access script variables
• control the keyboard and keyboard script
• determine script codes
• obtain character-type information
• directly access a script system's international resources
• tokenize text
• transliterate text
• replace the default routines for a 1-byte complex script system

Throughout these routine descriptions, unless otherwise noted, the Script Manager expects that

• there is a buffer containing text characters only; font and style information are stored separately
• the storage order of the characters--the order in which character codes are stored in memory--is their logical order, the order in which they would most naturally be entered from the keyboard
• all offsets within text buffers are zero-based and specified in bytes, not characters
• a valid graphics port exists, and the font of the port is set correctly; all text-related fields in the graphics port record reflect the characteristics of the text being manipulated

Assembly-language note

You can invoke each of the Script Manager routines that uses the _ScriptUtil trap with a macro that has the same name as the routine, preceded by an underscore. See "Summary of the Script Manager" at
the end of this chapter for a list of the routines that use the _ScriptUtil trap.
