CHAPTER 12
[2 Goto]
To shift program execution to a label (character string).
Entry: Goto character string
<Example>
Goto LOOP
[3 If]
Specifies conditional branches.
• Conditional branches start with the If command and are followed by the condition
statement and the branch destination when the condition is satisfied.
• Only the Goto command can be used following an “If” command.
• A space can be entered before the Goto command to make the program easier to
read.
Entry: If condition statement Goto character string
<Example>
If A = 1 Goto LOOP (If A = 1, then execution shifts to the Label LOOP. If A is not
equal to 1, the next program line is executed.)
[4 Gosub]
Shifts program execution to the sub routine starting with Label <character string>.
• The Gosub character string must be the same as the character string of the Label
indicating the start of the sub routine.
• Return is necessary at the end of the sub routine. When the Return statement is
executed, program execution shifts to the next command after the Gosub
statement.
• Up to 10 sub routines can be nested, i.e. 10 Gosub commands may be entered
before a Return command is required.
Entry: Gosub character string
<Example>
Gosub PART 1
[5 Return]
Ends the sub routine and shifts the program execution to the next line after the
Gosub statement that specified the jump to the sub routine.
Entry: Return
