Appendix A - Built-in Script Support / WorldScript II

Initialization Sequence

The startup code for enabling all available 2-byte script systems and script utility routines is in WorldScript II. WorldScript II is located in the Extensions folder; its file type is 'scri' and its creator is 'doub'.

At system startup, all extension files in the Extensions folder are executed; script files are executed before all other extensions.

At startup, WorldScript II does the following:

1. It gets the total number of international bundle ('itlb') resources from the
   System Folder.
2. For each bundle resource that belongs to a 2-byte script, WorldScript II
   • creates a script record and copies the byte-type table from the script's encoding/rendering ('itl5') resource into the script record
   • gets handles to all transliteration resources for that script and adds them to the script record
   • initializes the script's script record, a private data structure that holds information and addresses pertinent to that script
