Synopsis

Unofficial Name: DeselectAllVars

BCALL Address: 4A1D

Resets bit 7 of every variable's type byte in its symbol table entry. Bit 7 is used to determine whether the variable is selected in the new group and send/receive link contexts.

Inputs

  • None

Outputs

  • Bit 7 of every variable's type byte is reset

Destroys

  • All

Comments

This routine also resets bit 7 of each of the 35 bytes at 8694h. If the calculator is anything other than the 83+ Basic, it will also zero out the 32 bytes at 8697h, for whatever reason.
