== Synopsis ==
'''Official Name:''' MonReset

'''BCALL Address:''' 4C54

Resets window settings, loads dummy returns to all cxMain vectors, and clears several flags.

=== Inputs ===
* None

=== Outputs ===
* winTop, winLeft, winBtm set to fullscreen values
* Address pointing to "ret" loaded to all six context vectors

=== Destroys ===
* AF,BC,DE,HL

== Comments ==
This B_CALL is called upon exiting an app. Speculation is that it is some kind of cleanup after executing an app. Built-in and other external apps might not change all the context vectors, and this B_CALL could take care of that.

== Credits and Contributions ==
* '''JMan:''' For speculation about this B_CALL

== Synopsis ==
'''Official Name:''' Max

'''BCALL Address:''' 4057

Sets op1 to the larger of the two floating point numbers in op1 and op2.

=== Inputs ===
* op1 = floating point number
* op2 = floating point number

=== Outputs ===
* op1 = the bigger floating point number

=== Registers Destroyed ===
* AF, BC, DE, HL, OP3, OP4

== Comments ==
This is similar to the BASIC function Max().

== Example ==
Suppose op1=00h,80h,12h,00h,...
And op2=00h,80h,10h,00h,...
After B_CALL Max, op1=00h,80h,12h,00h,...
