Comments

Comments in the style of C and C++ can be included in CPO files.

For example:


x = intVar(1..10); // This is single line comment (ends by new line).
y = x +  /* This is another comment. */ + 5;
/*
 * And this is multi-line comment.
 */

White space

ASCII white space (space, tab) and end of line are ignored during the parsing. An exception is identifiers enclosed in quotes.
