 +==== Advantage Pac : Flag 21 ====
 +
 +I found that using some of the Advantage Pac programs (e.g. ''MATRX'' or ''CFIT'') would lead to ''AVIEW'' instructions in programs run subsequently to cause a ''HALT'' - requiring use of the <key>R/S</key> key.
 +
 +I was told via a question on the [[https://forum.swissmicros.com/viewforum.php?f=24 | Swiss Micros Forum ]] that this was likely to be due to the Advantage Pac setting ''FLAG 21'' (printer active) to help in its own presentation of information on the display. 
 +
 +''FLAG 21'' SET while ''FLAG 55'' is CLEAR (since there's no Printer Module active) causes AVIEW instructions to halt awaiting user intervention (<key>R/S</key> key)
 +
 +To restore things to //normal// : either ''CLEAR'' Flag 21 via ''CF'' or simply turn the calculator off and on again.
 +
 +See APPENDIX D in the HP41CX User Manual Volume 2 for a better explanation of the use of Flag 21 to control ''AVIEW'' behaviour.
