I created %ZSTART, having just learned about it. I included some minimal code to test it, as follows:%ZSTART
SYSTEM
WRITE "SYSTEM.",!
QUIT
JOB
WRITE "JOB.",!
QUIT
LOGIN
WRITE "LOGIN.",!
QUIT
CALLIN
WRITE "CALLIN.",!
QUIT
Now Terminal still works as normal, and sure enough I get "LOGIN" displayed, but when I start Studio I get an error message such as the following. I wonder what Caché ODBC has to do with it.
