220 Creating and Running Algorithms  
Comment Lines
Probably the most important element of programming is the comment. 
In older BASIC interpreters the comment line began with "REM" and 
ended at the end-of-line character(s) (probably carriage return then 
linefeed). Later BASICs allowed comments to also begin with various 
"shorthand" characters such as "!" or "'". In all cases, a comment ended 
when the end-of-line is encountered. In 'C' and the Algorithm Language, 
comments begin with the two characters "/*" and continue until the two 
characters "*/" are encountered. Examples:
/* this line is solely a comment line */
if ( a != b) c = d + 1;  /* comment within a code line */
/* This comment is composed of more than one line.
The comment can be any number of lines long and
terminates when the following two characters appear
*/
About the only character combination that is not allowed within a comment 
is "*/", since this will terminate the comment.
if(a <= 0) c=abs(a);
if(a != 0)
c = b / a;
if((a != b) && (a != c))
{
a = a * b;
b = b + 1;
c = 0;
}
if((a == 5) || (b == -5))
{
c = abs(c);
c = 2 / c;
}
else
{
c = a * b;
}
IF A<=0 THEN C=ABS(A)
IF A<>0 THEN
C=B/A
END IF
IF A<>B AND A<>C THEN
A=A*B
B=B+1
C=0
END IF
IF A=5 OR B=-5 THEN
C=ABS(C)
C= 2/C
ELSE
C= A*B
END IF
