7-14 Reference
GOTO
Syntax
GOTO label:
This is an unconditional branch instruction which causes program execution
to jump to, and continue from, the line specified by [label]. When declaring
a label and when indicating which label to go to, a trailing [:] must be written
with the label. The trailing [:] identifies the name as a label. This is different
to other programming languages.
If the
BACKGROUND task is to be continuously executed, a GOTO instruction
must be included.
Example BACKGROUND{
top: //this is the name of the label
IF #18.32 = 1 THEN
#1.21 = 100
ELSE
#1.21 = 0
ENDIF
GOTO top: //goto the line with the label [top:]
}
