List of supported keyboard layouts in PCOS 2.0h:
When reading an M20 ascii file (e.g. from a floppy) in a unicode environment, the characters depend on the language setting of the PCOS under which the file was originally created with. The following mapping can be used:
| M20 Alternate Graphics | { | | | } | [ | \ | ] | ~ | @ |
|---|---|---|---|---|---|---|---|---|
| Italian (0) | à | ò | è | ° | ç | é | ì | § |
| West German (1) | ä | ö | ü | Ä | Ö | Ü | ß | § |
| French (2) | é | ù | è | ° | ç | § | ¨ | à |
| English/ British (3) | { | | | } | [ | \ | ] | ‾ | @ |
| English/ American (4) | { | | | } | [ | \ | ] | ‾ | @ |
| Spanish (5) | ° | ñ | ç | ¡ | Ñ | ¿ | ‾ | § |
| Portugese (6) | ã | ç | õ | Ã | Ç | Õ | ° | § |
| Swedish Finnish (7) | ä | ö | å | Ä | Ö | Å | ‾ | @ |
| Danish (8) | æ | ø | å | Æ | Ø | Å | ¨ | ´ |
| Yugoslavian (10) | đ | ć | ž | Đ | Ć | Ž | č | Š |
| Norwegian (11) | æ | ø | å | Æ | Ø | Å | ¨ | ´ |
| Greek (12) | { | | | } | [ | \ | ] | ‾ | @ |
| French Swiss (13) | ä | ö | ü | à | ç | è | é | § |
| German Swiss (14) | ä | ö | ü | à | ç | è | é | § |
| Original German (15) | ä | ö | ü | Ä | Ö | Ü | ß | § |

Interestingly, two of these characters are part of the BASIC programming language ("\" is used as integer division, "@" is used as a prefix for call by reference variables). On the original machine, these characters must also be replaced by their corresponding national counterpart. As an example: On the German machine's keyboard, there is no Backslash, in order to perform an integer division of e.g. 10\3, one has to write "10Ö3".
