Comments are pieces of text used to annotate a program, and are technically anoth-
er form of whitespace. Comments are for the programmer’s use only; they are
stripped from the source text before parsing.

Use the apostrophe to create a comment:

' Any text between an apostrophe and the end of the

' line constitutes a comment. May span one line only.

There are no multi-line comments in mikroBasic PRO for AVR

Token is the smallest element of a mikroBasic PRO for AVR program, meaningful to
the compiler. The parser separates tokens from the input stream by creating the
longest token possible using the input characters in a left–to–right scan.

mikroBasic PRO for AVR recognizes the following kinds of tokens:

- keywords 
- identifiers 
- constants 
- operators 
- punctuators (also known as separators) 

Here is an example of token extraction. See the following code sequence:

end_flag = 0

The compiler would parse it into four tokens:

end_flag  ' variable identifier
=         ' assignment operator
0         ' literal

newline   ' statement terminator

Note that 

end_flag

would be parsed as a single identifier, rather than the keyword

end followed by the identifier _

flag

.
