Hi
Can't get context to work. Variable m_sContext doesn't appear to be used at all in the code after being declared.

Contextual reply seems to work once... appears to count entries in vector context list but if you try to do it twice by adding further context entries to the flat file database it seems to push them into the context vector list but does nothing with them and returns 'Bot doesn't understand' and goes to a random reply instead of continuing in context.

Can't quite work out what is going wrong and also why there is a prev_response or prev_input variable that could be used for context instead of adding in a special list that seems to duplicate what prev_response or prev_input does?

Am I missing something here?

Changes I made to script txt:

KWHAT IS YOUR NAME
RMY NAME IS CHATTERBOT13.
RYOU CAN CALL ME CHATTERBOT13.
RWHY DO YOU WANT TO KNOW MY NAME?
#
KSO THAT'S YOUR NAME
CMY NAME IS CHATTERBOT13.
CYOU CAN CALL ME CHATTERBOT13.
CWHY DO YOU WANT TO KNOW MY NAME?
RYES, THAT'S MY NAME
RYES IT IS.
#
KI LIKE THAT NAME
CYES IT IS
CYES, THAT'S MY NAME
RTHANKYOU FOR LIKING MY NAME
RI AM PLEASED YOU LIKE MY NAME
#
KDID YOU CHOOSE IT YOURSELF?
CTHANKYOU FOR LIKING MY NAME
CI AM PLEASED YOU LIKE MY NAME
RYES I DID CHOOSE IT MYSELF

For some reason the last block of text fails to work. I have tried other iterations but the code always fails to get context correct after working the first time.
