Each command line must parse as one of the following:
|
command list |
A command list is a sequence of one or more commands that the debugger are executes one after the other. |
|
comment |
A comment is a line that begins with a pound (#) character. The debugger ignores any text after an unquoted pound character. If the first non-whitespace character on a line is a pound character, the debugger ignores the whole line. |
The difference between a blank command line and a command line that is a comment is that a blank line entered from the keyboard causes the debugger to repeat the previous command and the comment line does not. The debugger treats blank lines that you do not not enter directly in the console as comment lines.
