Since goto doesn't exist, how do you jump to a label?
Thanks.

Use "If/Else/Endif", "Repeat/Until", "Select/Case/EndSelect", etc...
If you post some code of what you have so far or are trying to accomplish it would be easier to show how to code it properly.

Goto and Gosub no longer exist for a good reason. The code becomes very unreadable (spaghetti code).
I believe that you can change your code so that you no longer need Goto & Co.

Thanks. So instead of jumping over a section of code if something specific happens, I need to stick that section of code inside of an If-EndIf or a Select-EndSelect?
Does that sound right?
Speaking of labels, the page that mentions labels doesn't seem to have an example. If labels can't be jumped to, why do labels exist in SpiderBasic?

Labels are useful in DataSections (without a label you can't tell it what section of data to use)
Example...
Code: Select all
Restore last
For x=1 To 3
Read a
Debug a
Next
DataSection
first:
Data.i 1,2,3
last:
Data.i 7,8,9
EndDataSection

OK, thanks.
