Figure 11–26. Jam Player Flow Diagram (Part 2 of 2)
Execution of a Jam program starts at the beginning of the program. The
program flow is controlled using GOTO, CALL/RETURN, and FOR/NEXT
structures. The GOTO and CALL statements see labels that are symbolic
names for program statements located elsewhere in the Jam program. The
language itself enforces almost no constraints on the organizational
structure or control flow of a program.
1 The Jam language does not support linking multiple Jam
programs together or including the contents of another file into
a Jam program.
