- Try this:
-
- \<< ...
- 'PPAR' PURGE
- PICT PURGE
- PICT DROP
- ... \>>
-
- The non-programmable RESET command resets PPAR to its default values, resizes
- PICT to its default 131x64 size, and erases the contents of PICT. This
- little program segment does the same thing. For more information, see "HP48
- Graphics," page 105 and 272.
