# Checklist for correct CML2
|
||||
# 1) Have you defined a prompt for each menu, choice_type?
|
||||
# 2) Have you defined a default for each symbol?
|
||||
# 3) Have you put 'symbols' keyword before each symbol, menu and choice?
|
||||
|
||||
|
||||
# Important note on derived symbols
|
||||
# DO NOT place any declaration for derived symbols like normal symbols,
|
||||
# otherwise the derivation will be silently ignored, and you will be left
|
||||
# wondering why.
