Starting the CLI
The only real difference between the last two examples is the first few lines
in the file. In this second example, the shell ignores the backslash continuation
character; Tcl processes it. This means that the shell executes the
exec command while Tcl will ignore it.
Starting Your Program
The CLI lets you start debugging operations in several ways. To execute
your program from within the CLI, enter a dload command followed by the
drun command.
If your program is launched from a starter program such as srun or yod, use the drerun
command rather than drun to start your program. If you use drun, default arguments
to the process are suppressed; drerun passes them on.
The following example uses the totalviewcli command to start the CLI. This
is followed by dload and drun commands. Since this was not the first time
the file was run, breakpoints exist from a previous session.
In this listing, the CLI prompt is “d1.”. The information preceding the greater-than
symbol (>) symbol indicates the processes and threads upon which the current command
acts. The prompt is discussed in “About the CLI Prompt” on page 207.
