Synopsis

Official Name: NewContext0

BCALL Address: 4033

Loads one of the TIOS builtin apps.

Inputs

• A = context equate (see cxCurApp)

Outputs

• Context vectors set to the desired app
• others?

Destroys

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

Comments

This B_CALL puts away the current app, loads the context vectors for a particular builtin app, and calls the appropriate initialization code.

In most cases, this routine will return to the caller after initializing the given app, but for some apps, the page in port 6 will not be restored correctly. Using NewContext instead may be a better choice.
