Synopsis

Official Name: NewContext

BCALL Address: 4030

Loads one of the TIOS builtin apps.

Inputs

• A = context equate (see cxCurApp)

Outputs

• Context vectors set to the desired app

Destroys

• Many additional side effects are possible depending on the app selected

Comments

This routine (similar to NewContext0) puts away the current app, loads the context vectors for a particular builtin app, and calls the appropriate initialization code.

Unlike NewContext0, this routine saves and restores the current page in port 6 regardless of the app selected. It also sets (kbdKey) to zero.
