If you start Character Animator in the same directory as that in which you run the program that is to be debugged, the program will attach to the waiting Character Animator process.
For example, in one session enter:
cd /home/user/program/debug cobanimsrv
Character Animator is now waiting for a program to start in the /home/user/program/debug directory. Therefore, if in another session you change to the same directory and start a program by entering:
cd /home/user/program/debug cobrun prog1.int
prog1.int attaches to the waiting Character Animator process; the Character Animator main screen is displayed and the cursor is placed on the first line of prog1.int.
