The following code give error when used in code" path or filename not found"

public cbi_ptxt
store "c:\temp\"+sys(3) + ".txt" to cbi_ptxt
SET PRINTER to (cbi_ptxt)

I want to redirect a report form to a file. I will also be using the ADDITIVE keyword in my code to append additional reports.

When I type each line at the command prompt, there is no error displayed

This code worked perfectly good in FP25 DOS
VFP 7.0 don't seem to like it. Any Suggestions ??? workarounds ??
