GOTO

[All Models]

Purpose

Branches unconditionally to a specified branch destination.

Format

            { branch destination line number }
            {  └─────────────┬─────────────┘ }
            {           Line number          }
   GOTO     {                                }
            {    # program area number       }
            {      └────────┬────────┘       }
            {      Single character; 0~9     }

Sample

GOTO   1000
GOTO   #7

Parameters

1. branch destination line number: Integer in the range of 1 <= line number <= 65535
2. program area number: Single character, 0 ~ 9

Explanation

1. Specifying a line number causes program execution to jump to that line number in the current program area.
2. Specifying a program area number with GOTO #n (where n is 0-9) causes program execution to jump to the first line number of the specified program area. Execution continues in that program area. Unlike GOSUB #n, there is no return to the original program area.
3. A UL error is generated when the specified line number does not exist.

• IF…THEN…ELSE

Sample Program

10  PRINT "PRESS [BRK]";
20  PRINT "TO HALT EXECIUTION" ;
30  GOTO 10

Line 30 returns execution to line 10.

This loop continues until BRK is pressed.
