Re: st: True batch mode

Sergiy,

The problem with method 2. is that -capture- suppresses all output (why, 
I don't know).  I hope I don't have to resort to 3. or 4., just to get 
behavior that I should expect out-of-the-box.

So I tried approach 1....

---- file stata.bat ----
@echo off

start "title needed" /w "c:\Program Files\Stata10\wstata.exe" /e do %1

echo Exit code: %errorlevel%
---- end ----

It "works" in a sense; however, the error code is 0 even if there is an 
error in the do file.  And if I try to trap errors in the do file using 
-capture-, I don't get any output when it runs correctly.

This is ridiculous.  You shouldn't have to pull teeth to do this.  For 
batch processing, Stata should behave like everything else -- run in the 
foreground and return an appropriate exit code.  It's nice to have the 
OPTION of running in the background, but it shouldn't be shoved down 
your throat.
