Hello all! My company has been switching from $zf(-1) to $zf(-100) like many companies have been. I have been doing fine with 1 argument windows commands such as: set errorfile = "D:\folder\error.txt" set outputfile = "D:\folder\output.txt" set options(1) = "" set options(2) = "D:\ThomasTools\" w $zf(-100,"/SHELL /STDERR="\_errorfile\_" /STDOUT="_outputfile, "dir", .options) same as w $zf(-1,"dir D:\ThomasTools\ >> D:\folder\output.txt") I get a valid response and everything works correctly. I am having troubles with commands that would take multiple arguments however.  valid reponse with w $zf(-1, "type D:\folder\file1.txt >> D:\folder\file2.txt") set options(1) = "" set options(2) = "D:\folder\file1.txt" set options(3) = ">>" set options(4) = "D:\folder\file2.txt" w $zf(-100, "/SHELL /STDERR="\_errorfile\_"/STDOUT="_outputfile,"type",.options) even tried with set options(1) = "" set options(2) = "D:\folder\file1.txt" set outputfile = "D:\folder\file2.txt" w $zf(-100,"/SHELL /STDERR="\_errorfile\_"/STDOUT+="_outputfile,"type",.options) seemed logical but both are giving me errors. Anyone care to help me hammer this out?
