3.3. Deleting Parameters

You can delete specific parameters in two ways:

Issue the "=" command, leaving the right-hand side of the command blank. For example, to delete the QR parameter issue this command:
```
QR=
```
Issue the *SET command, but do not specify a value for the parameter. For example, to delete the QR parameter via the *SET command, issue the command as follows:
```
*SET,QR,
```

Setting a numeric parameter equal to zero does not delete it. Similarly, setting a character parameter equal to empty single quotes (` `) or placing blanks within single quotes does not delete the parameter.
