Having trouble Windows command line SORT via SHELL

[GTC]

Bad news here:  It works fine for me

Code: (Select All)

$console:only
sort$ = "sort " + "input.txt" + " >> " + "output.txt"
shell sort$
system

Something to try - probably won't make a difference, but change "sort " to "sort.exe ".  Both work the same here.

Thanks to the tip from @SMcNeill, now that I can hold the output screen and read the message, SORT is saying "Input file specified two times." ... which is not the case!

At command line level, the only way to get that error message is to omit the redirect operator. However my command string includes the redirect operator so this is just nuts.
