The single quote in the thisform.custAddress shouldn't cause such problem. Anyway, to make the code readable you can use square brackets as string delimiters.

filetext1 = ["5" "] + c67invhd.inv_cardnu + ;
	[" "] + c67invhd.inv_cardex + [" "] + allt(str(thisform.charges,8,2)) + ;
	[" "] + str(c67invhd.inv_ordnum,8,2) + [" "] + c67invhd.inv_cardap + ;
	[" "] + thisform.custAddress + ["]
