in strvar starting at Index
for Len chars.

bytes starting a byte Index.
| Parameter | Description (Mid Function) |
|---|---|
| S$ | Copy chars from this string value. If this value is Null then Null is returned. |
| Index | Start copying chars starting at this index value. If the string is not that long then return a null string. |

| Parameter | Description (Mid Assignment) |
|---|---|
| strvar | Change part of this string. |
| Index | Change strvar starting at this index value. If the string is not that long then it is not changed. |
| Len | The number of chars copied is smallest of: the value of Len, the length of S$ and the remaining length of strvar. (If this value is omitted then the number of chars copied is the smallest of: the length of S$ and the remaining length of strvar.) |
| S$ | Copy chars from this string value. |
