===== FLOW CONTROL USING GOTO WITH LINE NUMBERS =====
==== PURPOSE ====
This example will show the use of ''GOTO'' keyword. The main code will change the border color (yellow and black). Each color will last 100 milliseconds on the screen. The border color is changed using the ''COLOR BORDER'' instruction, using ''YELLOW'' and ''BLACK'' constants. To wait for a specific amount of time the ''WAIT'' command will be used, with the ''MS'' (milliseconds) unit of time.
==== SOURCE CODE ====
120 COLOR BORDER YELLOW
125 HOME: PRINT "YELLOW"
130 WAIT 100 MS
140 COLOR BORDER BLACK
145 HOME: PRINT "BLACK "
150 WAIT 100 MS
160 GOTO 120
