Lexical Analysis (1 Viewer)

[honky tonk]

I understand that the lexical analysis procedure:

• Uses delimiters in source code to break the program into single lines, and
• Scans each character in the line and removes remarks, indentation and spaces

but what else does it do? I've read several summaries and many of them contradict each other or are too 'wordy' for my liking.

Can anyone help?

well, this is what i have in my notes:
- goes through and find key words
- assign keywords to token
-store tokens in a symbol table or token dictionary
- check for type mismatches, makes call to subprogram
- tokens are them passed to the syntactic analysier

hope this helps

p.s. i think the book 'heinemann' explains it better

Kamankitty seems to have said exactly what I would have said. Go with that definition and you should be fine.
