I'm sorry but I cannot see how single quote in the address could cause such error. Here's the test I ran and no error was generated.

m.inv_cardnu = "ABC"
m.inv_cardex = "EFG"
m.charges = 125.63
m.inv_ordnum = 1234567.89
m.inv_cardap = "LKIOM"
m.custAddress = "155 ' Willowbrok"

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

Can you post values for all properties and fields?
