OSBYTE &46 (70) - Set country number
On entry: X=&00+n - set or read country
X=&80+n - reserved
n=&00 - set to default
n=&7F - read current setting
On exit, X=0 - if specified country not supported
X<&80 - previous country
X>&7F - OSBYTE call not supported
This call allows both the keyboard and alphabet (font) to be set both at once.
The country is specified with a country number 0-99, this sets the appropriate keyboard and the appropriate alphabet (font) for that country by redefining the font with VDU 23 sequences. See OSBYTE &47 for country numbers.
Selecting the default country with X=&00 selects the default country set with *CONFIGURE COUNTRY. If there is no default country set it falls back to UK or BBC as appropriate.
OSBYTE &47 allows the keyboard and alphabet (font) to be set individually. The country number is stored in the OSBYTE &F0 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
Implementation
Implemented in the Master Internationalisation ROM, RISC OS kernel and keyboard handlers, and 8-bit keyboard extensions.
OSBYTE &46 (70) - Apple Mac BBC BASIC
- FX70,n,n does something on Mac Basic
