TC (Tell Code)
[Status]
DESCRIPTION:
The TC command returns a number between 1 and 255. This number is a code that reflects why a
command was not accepted by the controller. This command is useful when the controller halts execution
of a program at a command or when the response to a command is a question mark. Entering the TC
command will provide the user with a code as to the reason. After TC has been read, it is set to zero. TC 1
returns the text message as well as the numeric code.
NOTE:_ED returns the line number that last had an error.
ARGUMENTS: TC n
n=0 returns code only
n=1 returns code and message
