Redirection of executable's stardard & error output

[ssimop]

With the following command, from the DOS prompt, I can redirect the output of an executable to a DOS folder :

lstcat 2>&1 1>"C:\tmp\tzuni.txt"

However, I failed to execute this command through a QM macro. Primarily I used the statement'

run "C:\MSDEV\ses\spu\gamma\lstcat.exe" "2>&1 1>''C:\tmp\tzuni.txt''"

but it failed. I would appreciate any advice. Many thanks in advance.
