ugBASIC User Manual

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.

 
     CLS
 
 label: 
     COLOR BORDER YELLOW
     HOME: PRINT "YELLOW"
     WAIT 100 MS
     COLOR BORDER BLACK
     HOME: PRINT "BLACK "
     WAIT 100 MS
     GOTO label
