rem -- start a comment
rem Hey, this is a comment
# this is a comment too
// even this
print "Not a comment" # This is an error!!
print "Not a comment":// But this is again a valid comment
print "Not a comment" // even this.
print "Not a comment" rem and this!
rem introduces a comment (like # or //), that extends up to the end of the line.
Those comments do not even need a colon (':' infront of them); they (rem, # and //) all behave alike except for #, which may only appear at the very beginning of a line; therefore the fourth example in the synopsis above (print "Not a comment" # This is an error!!) is indeed an error.
Note, that rem is an abbreviation for remark. remark however is not a valid command in yab.
Finally note, that a comment intoduced with '#' may have a special meaning under BeOS; see the entry for # for details.
rem comments on data structures
# are more useful than
// comments on algorithms.
This program does nothing, but in a splendid and well commented way.
