OSBYTE &47 (71): Set alphabet or keyboard
On entry: X=&00+n - set or read alphabet (font)
X=&80+n - set or read keyboard
n=&00 : set to default
n=&7F : read current setting
n=1-99 : Countries
n=100-126 : Alphabets
On exit, X=0 - specified alphabet/keyboard not supported
X<&80 - previous alphabet/keyboard
X>&7F - OSBYTE call not supported
While OSBYTE &46 sets both the keyboard and alphabet (font) in one action, this call allows each to be set individually.
Selecting an alphabet redefines the font with VDU 23 sequences. The alphabet can be specified with a country number 0-99, the appropriate alphabet for that country is then selected. Or the alphabet can be selected with the specific alphabet number 100-126. Selecting the default alphabet with X=&00 selects the appropriate alphabet for the currently selected country set with OSBYTE &46.
The keyboard can only be selected by specifying a country number, selecting a keyboard with an alphabet makes no sense. Selecting the default keyboard with X=&80 selects the appropriate keyboard for the currently selected country set with OSBYTE &46.
On 8-bit systems the keyboard number is stored in the OSBYTE &AD variable, on 32-bit systems it is stored in a non-OSBYTE variable.
- *COUNTRY parses the parameter and calls OSBYTE &46,n
- *ALPHABET parses the parameter and calls OSBYTE &47,&00+n
- *KEYBOARD parses the parameter and calls OSBYTE &47,&80+n
