Forcing an interrupt in the Atari [Altirra|http://www.virtualdub.org/altirra.html] emulator\\

\\
.basic_rebuildvnt\\
.basic_rebuildvvt\\

The 2 lines executed in Altirra, do the following things:\\

.basic_rebuildvnt ; Rebuild BASIC variable name table\\
.basic_rebuildvvt ; Rebuild BASIC variable value table\\
