Action
Jump to the specified label.
Syntax
GOTO label
Remarks
Labels can be up to 32 characters long.
When you use duplicate labels, the compiler will give you a warning.
Valid labels
- A valid label ends with a colon (:)
- A valid label starts on the line.
- There is no space between the label name and the colon.
Label: is a valid label.
Label : is invalid
Since a colon is also used to separate multiple lines of code, the label must be the only code on the line.
For example :
print "abc" : print "klm" 'these lines are separated by a colon.
abc: : print "klm" 'this is invalid since the line starts with a label.
Besides using a label you can also specify an address. GOTO &H0000 would jump to the reset vector of the processor.
Because numeric addresses can be specified, it is advised to use non-numerical labels.
