The [EOF](EOF) function indicates that the end of a file has been reached.
|
|
|
|
## Syntax
|
|
|
|
> endReached%% = EOF([#]fileNumber&)
|
|
|
|
## Description
|
|
|
|
* fileNumber& is the number of the file being read. **#** is not required.
|
|
* Returns 0 until the end of a file. This avoids a file read error.
|
|
* Returns -1 (true) at the end of the file.
|
|
* **Note that [GET](GET) can return invalid data at the end of a file.** Read [EOF](EOF) after a GET operation to see if the end of the file has been reached and discard last read.
