So I checked, and similarly to what's described on the SAVE page, cancelling a load saves -1 to the RESULT system variable while a successful load saves 1. And assuming it's the same as SAVE, a load failing would presumably save 0 to RESULT.
LOAD
Root / Documentation / [.]
Load a program, stored in a TXT file, to a program slot.
* Syntax
```sbsyntax
LOAD file$ {, slot% }
```
|* Input | Description |
| `file$` | The name or path of the file to load. |
| `slot%` | The program slot used (optional; default 0.) |
The `file$` parameter may optionally start with `TXT:`; e.g. `"TXT:FOO"` and `"FOO"` refer to the same file. Files from other projects can be loaded by specifying the project path; e.g. `"BAR/FOO"` or `"/FOO"`
* Examples
```sb4
'load FOO into slot 0
LOAD "FOO"
LOAD "TXT:FOO"
LOAD "FOO",0
```
```sb4
'load FOO from the project BAR
LOAD "BAR/FOO"
```
