The data of a file of type 00 is a BASIC program in the form it has in the Oric’s memory,
starting at $0501. The table here is the keyword table of the BASIC 1.1 ROM (the Atmos’s), checked word
by word against a ROM image. The ROM 1.0 of the first Oric-1s was not available to check against.
Lines
| Size | Name | Description |
|---|---|---|
| 2 | Link | The address of the next line, low byte first (in memory, so counted from the start address). |
| 2 | Line number | Low byte first. |
| n | Text | Characters, with each keyword as one token byte (80 to F6). |
| 1 | End of line | 00. |
Text in quotation marks, and everything after REM (9D), is stored as typed.
The first line of a program saved from BASIC is at $0501, so the first link is at least
$0505.

A link of 00 00 in place of the next line. With the 00 that ends the last line, a program
ends with three zero bytes, as above.

such as {F7}.
