THE 'SKIP CONSTANTS' SUBROUTINE
This subroutine is entered with the HL register pair holding the base address of the calculator's table of constants and the A register holding a parameter that shows which of the five constants is being requested.
The subroutine performs the null operations of loading the five bytes of each unwanted constant into the locations 0000, 0001, 0002, 0003 and 0004 at the beginning of the ROM until the requested constant is reached.
The subroutine returns with the HL register pair holding the base address of the requested constant within the table of constants.

33F7	SKIP-CONS	AND	A	The subroutine returns if the
33F8	SKIP-NEXT	RET	Z	parameter is zero, or when the
				requested constant has been
				reached.
		PUSH	AF	Save the parameter.
		PUSH	DE	Save the result pointer.
		LD	DE,+0000	The dummy address.
		CALL	33C8,STK-CONST	Perform imaginary stacking of
				an expanded constant.
		POP	DE	Restore the result pointer.
		POP	AF	Restore the parameter.
		DEC	A	Count the loops.
		JR	33F8,SKIP-NEXT	Jump back to consider the value
				of the counter.

THE 'MEMORY LOCATION' SUBROUTINE
This subroutine finds the base address for each five byte portion of the calculator's memory area to or from which a floating-point number is to be moved from or to the calculator stack. It does this operation by adding five times the parameter supplied to the base address for the area which is held in the HL register pair.
Note that when a FOR-NEXT variable is being handled then the pointers are changed so that the variable is treated as if it were the calculator's memory area (see address 1D20).
3406	LOC-MEM	LD	C,A	Copy the parameter to C.
		RLCA		Double the parameter.
		RLCA		Double the result.
		ADD	A,C	Add the value of the parameter
				to give five times the original
