# Ocean-240.2 MS Basic
|
||||
|
||||
Source codes of Microsoft Basic for Ocean-240.2 computer (BASIC-80 R.5/240).
|
||||
Based on Microsoft BASIC-80 v5.21.
|
||||
|
||||
- In Z80 mnemonics, but limited for i8080 instruction set.
|
||||
- I tried to keep the original label names as they are in the source codes published by Microsoft.
|
||||
- Small bug with cond jump to data table fixed.
|
||||
|
||||
## Extended Ocean-240.2 operators
|
||||
|
||||
* CLS - Clear screen;
|
||||
* SCRN - Set graphics mode;
|
||||
* COLOR - Set foreground colors;
|
||||
* CURS - Move cursor to specified position;
|
||||
* PLOT - Draw line from cursor pos to specified position;
|
||||
* RECT - Draw rectangle with diagonal from cursor pos to specified position;
|
||||
* GPRINT - Print graphics screen to printer;
|
||||
* TONE - unimplemented;
|
||||
|
||||
