Unofficial Name: MarkTempDirty
BCALL Address: 4297
This BCALL checks if the name in OP1 has 24h in (OP1+1), and if so, calls FindSym on it and marks its VAT entry as "dirty" (setting bit 7 of the first byte of its VAT entry).
- OP1: name of variable
- Variable marked as dirty only if OP1+1 contained 24h
- Zero Flag: NZ if failure
This BCALL sets bit 7 of the first byte in the variable's VAT entry. That might mean the variable is "dirty". The 24h byte indicates a temporary variable.
