Routines
The Script Manager routines documented in this section allow you to
Throughout these routine descriptions, unless otherwise noted, the Script Manager expects that
- 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
- 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
_ScriptUtiltrap 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_ScriptUtiltrap.
