Answer 1

try this to avoid trailing spaces in %logdir% :

set "logdir=d:\ora\log"
>>"%logdir%\hot_gen%date:~0,4%%date:~5,2%%date:~8,2%.log" call d:\Hot_gen.bat %B_SCRIPT_TARGET% %B_BACKUP_TARGET%

Answer 2

The value of the environment variable logdir has a space at the end.

This is most likely because you've got a line somewhere that says

 set logdir=d:\ora\log

and there's an extra space at the end of the line.
