Function Name: INDCMP

Purpose: CMP (cmpvec),Y to any bank
Call address: $FF7A (hex) 65402 (decimal)
Preparation:

	Registers:	.A = data
			.X = bank (0-15)
			.Y = index
	Memory:		setup indirect vector
			setup CMPVEC ($2C8) pointer
	Flags:		none
	Calls:		none
Results:
	Registers:	.X used
	Memory:		none
	Flags:		status valid

Description: INDCMP enables applications to compare data to any other bank. After you set up CMPVEC ($2C8), it calls GETCFG to convert the bank number and JMP's to code in common (shared) RAM at $2BE which switches banks, compares the data, restores your bank, and returns. When calling a nonsystem bank, the user should take necessary precautions to ensure that interrupts (IRQ's and NMI's) will be handled properly (or disabled beforehand).

EXAMPLE:

	LDA	#$00	;setup to verify $2000
	STA	$FA
	LDA	#$20
	STA	$FB
	LDA	#$FA
	STA	$2C3
	LDA	data
	LDX	#$01	;in bank 1
	LDY	#$00
	JSR	$FF7A	;CMP ($FA,RAM 1),Y
	BEQ	same
