mikoBasic PRO for dsPIC30/33 and PIC24

MikroElektronika

Comments are pieces of text used to annotate a program, and are technically another 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:

There are no multi-line comments in mikroBasic PRO for dsPIC30/33 and PIC24

Token is the smallest element of a mikroBasic PRO for dsPIC30/33 and PIC24 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 dsPIC30/33 and PIC24 recognizes the following kinds of tokens:

- keywords 

- identifiers 

- constants 

- operators 

- punctuators (also known as separators) 

Token Extraction Example

Here is an example of token extraction. Take a look at the following example code sequence:

end_flag = 0

First, note that 

end_flag

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

end

 followed by the identifier 

_flag

.

The compiler would parse it as the following four tokens:

end_flag   ‘ variable identifier

=         ‘ assignment operator

0         ‘ literal

   ‘ statement terminator
