currently the vanilla book is a more effective tool for programming in TIS-3D as it allows you to write programs that are more then 20 lines long (despite normal server config allowing for 40 lines of execution)
this could (or probally would) be implemented along side #158

another possible solution could be a way to "link" pages so that it basically combines them one after the other

i just bound out the #BWTM pre-processor exist
why is this not documented in the book

(along with the mutiple redstone sources making execution faster)

The multi-page macro is documented in the code bible page. The "overclocking" is hinted at in the main manual page.
