1.6.4. Implement a command that has identical functionality

[<<<] [>>>]

This macro helps to implement a command that has identical functionality as another command. You can see examples for it in the looping construct. There is a wide variety of looping construct to implement all looping facilities that BASIC programmers got used to. However the loop closing commands more or less behave the same. For example the command next behaves exactly the same as the command while

Also note that the identical behaviour does not mean that one command can be used instead of the other. There are conventions that the BASIC language requires and the syntactical analyzer does nto allow to close a FOR loop using a WEND command.

To present an example on how to use this macro we have copied the code of the comman NEXT:
