/* 
 * call-seq:

 * The number is formed by converting the major, minor, and revision
 * numbers into two-decimal-digit numbers and appending them together.
 * For example, version 7.4.2 will be returned as 70402, and version
 * 8.1 will be returned as 80100 (leading zeroes are not shown). Zero
 * is returned if the connection is bad.
