Whitespace
Whitespace is a collective name given to spaces (blanks), horizontal and vertical tabs, newline characters and comments.
Whitespace can serve to indicate where tokens start and end, but beyond this function, any surplus whitespace is
discarded.
For example, the two sequences
var i : char;
j : word;
and
var
i : char;
j : word;
are lexically equivalent and parse identically.
var
i
:
char
;
j
:
word
;
Newline Character
Newline character (CR/LF) is not a whitespace in Pascal, and serves as a statement terminator/separator. In mikroPascal
PRO for dsPIC30/33 and PIC24, however, you may use newline to break long statements into several lines. Parser will
rst try to get the longest possible expression (across lines if necessary), and then check for statement terminators.
Whitespace in Strings
The ASCII characters representing whitespace can occur within string literals, in which case they are protected from
the normal parsing process (they remain a part of the string). For example,
some_string := ‘mikro foo’;
parses to four tokens, including a single string literal token:
some_string
:=
‘mikro foo’
;
