# Data Interchange Format
|
||
|
|
|
||
|
|
Files starting with `TABLE` followed by a newline marker followed by `0,1`
|
||
|
|
should be interpreted as DIF.
|
||
|
|
|
||
|
|
There exists a technical specification from 1983.
|
||
|
|
|
||
|
|
### Encoding
|
||
|
|
|
||
|
|
The specification includes a Pascal procedure for reading a string. There is an
|
||
|
|
error in handling double quotes:
|
||
|
|
|
||
|
|
```pascal
|
||
|
|
if str[1] = '"' { strip quotes }
|
||
|
|
then begin
|
||
|
|
delete (str, 1, 1);
|
||
|
|
delete (str, pos('"', str), length(str) - pos('"', str) + 1)
|
||
|
|
end
|
||
|
|
```
|
||
|
|
|
||
|
|
It does not correctly handle `"` characters in strings. Writers should use `""`
|
||
|
|
(similar to CSV encoding). The following DIF snippet represents `"`:
|
||
|
|
|
||
|
|
```dif
|
||
|
|
1,0
|
||
|
|
""""
|
||
|
|
```
