Hi Chief, ;-)
I changed the script as you indecated and it prints the following:
testREnv compiling.................
Command : C:\R\bin\x64\Rterm.exe --no-save
R stopped!
I tried to run the complete command from a cmd and this start up Rterm.exe
perfectly. I get the prompt and can leave with q() as expected.
From the zorro script Rterm.exe seems to stop as printed by the zorro script.
I hope you have a suggestion of what to do.
