Parsing Key Definitions

If the mnemonic is not found in the terminal definition table, the key definition table is then searched. The parse table for key definitions is an array of KEYDEF structures. The KEYDEF structure has members for the following:

• nPointer to mnemonic for keycode
  
  
• nPointer to key definition string
  
  
• nNumber of keystrokes needed to generate the keycode (based on length of key definition string)
  
  
• nKeycode generated by sequence of keystrokes
  
  
• nPointer to a key label string

If the mnemonic is found in the key definition table, the initialization routine allocates memory for the string specified in the field and places a pointer to that string in the structure for that mnemonic. Also, the number of keystrokes is determined and set within that structure.
