Bad function number.

[Robert Repko]

I have an import routine that I have used before but now I am getting a 'Bad function number' error when I try to import data.
The file I am trying to import is a comma delimited ascii file.  It resides on c:\tmp and is called 2016payroll.csv
My processing table is:

nxtimp:::
::import ascii imp=c:\tmp\2016payroll.csv r=\n f=, o=" c=":
:not imp:end:
::lookup irs = 1099  r=free  -n:
::irs(11)=imp(2):
::irs(12)=imp(1):
::write irs
::goto nxtimp
The complete error is:
*** A System Error Has Occurred ***

On File: c:\tmp\2016payroll.csv

Output Processing
Line Number: 2

import ascii imp=c:\tmp\2016payroll.csv r=\n f=, o=" c="
^
Bad function number.

I don't see the problem.  Might I add that I am trying to import on a Windows 10 system (maybe that's my problem)
Does anyone see what I am missing?
