Purpose: Ends execution of a program. Used to control flow of logic through a given program.
Format: END
Example: 100 REM CHECK IF THE BOILERS ARE RUNNING
110 IF NOT BOILER-S THEN END
120 REM ONLY EXECUTE THE NEXT LINES IF THE BOILERS ARE RUNNING
130 START PUMP101
Programming tip:
GOTO statements, END statements and similar jumps in the basic programming language can lead to code which is hard to debug.
Logic with a lot of GOTOS and jumps is referred to as spaghetti code, use these statements sparingly.
The above example can be done with the same logic below without using the END command
BOILER is an output, shows us the boiler is asked to come on.
BOILER-S is an input which shows that the boiler is actually running.
100 IF BOILER THEN START PUMP101 ELSE STOP PUMP101
110 IF NOT BOILER-S THEN STOP PUMP101
