This Instruction can be used as an alternative to the "loop:" or "goto loop" instructions to identify the main block of an R3 program.

Syntax

__main_loop__

Validity

Task

Note

If break is present, no code is executed until end_main_loop.

The behavior of the __main_loop__ and end_main_loop instructions are analogous to the while and end_while construct with condition always true

Example of use:

; I call an initialization routine

call initParam

; start the main loop

__main_loop__

; main loop instruction

 ...

; I measure the duration of the main loop and store the value in the variable T1

 T1 = loop_time()

; I run statistics on the duration of the main loop

 returns = statistics(T1, statT1)

; end of main loop --> return to beginning

end_main_loop

Example of use:

; I call an initialization routine

call initParam

; start the main loop

__main_loop__

; main loop instruction

 ...

; if the value of the variable "finished" is equal to 1 I exit the loop,

; then the instrictions from this point to the end of the loop will not be executed

 _if (finished)

 break

; other main loop instructions

 ...

; end of main loop --> return to beginning

end_main_loop

; other instructions outside the main loop
