The problem you are encountering is like due to the fact that the
pathname buffer you have defined is not set up as a class 0 input
string.  Class 0 input strings require a single length byte which
holds the length of the pathname which follows.

Here is an example of what you might try:

creFile	jsr	$BF00		;ProDOS mli entry point
	dfb	$C0		;   CREATE FILE
	da	creParm		;   CREATE FILE PARAMETERS
	bcs	oops		;oops!  had a boo-boo.  :)
	bcc	saright		;everything is 'saright'

creParm	dfb	$07		;seven parms in the creation table
	da	crePath		;pointer to class 0 pathname
	dfb	%11100011	;bit 7, 1 = destroy enable
				;    6, 1 = rename enable
				;    5, 1 = back-up needed
				;  4-3, 0 (must be because reserved)
				;    2, 0 = not invisible
				;    1, 1 = write enable
				;    0, 1 = read enable
	dfb	$06		;binary file type (why not! :)
	da	$4000		;auxilliary type (default load addr)
	dfb	$00		;storage type (default to seedling)
	dfb	$00		;current date is creation date
	dfb	$00		;current time is creation time

crePath	dfb	$0F		;the pathname is 15 characters long
	asc	'/THIS/IS/A/PAIN'

I hope that you find this helpful.  Let me know if this works.
