Synopsis
Official Name: ZIfRclHandler
BCALL Address: 4A65h
Returns whether or not a Rcl handler (the function that occurs when you press 2nd+Rcl) is currently active.
Inputs
None
Outputs
- Zero Flag: Set if Rcl handler is active, reset otherwise.
Registers Destroyed
- DE, HL
Comments
This B_CALL works by simply comparing the address of cxMain to whatever it should be when the Rcl handler is active. Ironically cxPage is not checked.
