PREFIX Name
Specification:
| Set the current prefix to Name. |
Description:
Every name in a program is either complete or incomplete. A name is complete, if it starts with a colon (:), otherwise it is incomplete. Incomplete names are completed by adding the current prefix to them.
At the very beginning of assembling a program, the current prefix is just the colon (:). This situation can be restored any time by saying "PREFIX :".
