Source file contains a program in Jam language. Jam program consists of a sequence of
statements. Jam statement consists of a label, which is optional, an instruction, and
arguments, and terminates with a semicolon (;). Arguments may be literal constants, variables,
or expressions resulting in the desired data type (i.e., Boolean or integer). Each statement
usually occupies one line of the Jam program, but this is not required. Line breaks are not
significant to the Jam language syntax, except for terminating comments. An apostrophe
character (') can be used to signify a comment, which is ignored by the interpreter. The
language does not specify any limits for line length, statement length, or program size. More
