Title: Rewrite
| Old | New | Line | |
|---|---|---|---|
| 1 | + | The [[Procedure|procedure]] [`rewrite`](https://www.freepascal.org/docs-html/rtl/system/rewrite.html) clears and opens a file for writing. If the file did not exist, it is created. | |
| 2 | + | ||
| 3 | + | ## signature | |
| 4 | + | ||
| 5 | + | - `rewrite(var destination: text)` | |
| 6 | + | - `rewrite(var destination: file of T)` where `T` is an acceptable record type | |
| 7 | + | - `rewrite(var destination: file; recordsize: longInt = 128)` ([[FPC]] extension) | |
| 8 | + | ||
| 9 | + | ## behavior | |
| 10 | + | ||
| 11 | + | After invoking `rewrite` it is guaranteed that | |
| 12 | + | ||
| 13 | + | - the destination file is completely undefined (i. e. empty), | |
| 14 | + | - the writing cursor is at the beginning of the file, and | |
| 15 | + | - the file is writable and non-readable. | |
