    I think your problem is that you're confusing the assembler with trying to
    subtract an address from a constant.

I would suggest having something like the following:

			ORG	100H	; if you've got a COM file.
	Beginning	LABEL	BYTE
	...
	Loader	LABEL	BYTE
	Loader_offset	EQU	Beginning-Loader
	...

You could alternatively try something like:

	CODE	SEGMENT	BYTE	'CODE'
		; Dang! I can't recall the full syntax for the SEGMENT
		; directive, since mostly use the simplified CODESEG
		; DATASEG, and STACKSEG directives anyway.
	...
	Loader	LABEL	BYTE
	Loader_offset	EQU	CODE:100H-Loader
	...
	ENDS
