I am new to PROIV and SuperLayer. I want to know what is Superlayer and how it is related to PROIV. Also I would appreciate if someone could provide any documentation or link on SUPERLAYER.

SuperLayer is a layer above ProIV that allows a few interesting programming methods.
I think it is now solely used by Glovia and even they are attempting to phase it out.

Its a long time since I used SL (1995-6)

I would descrive Superlayer as an alternative development environment to the Pro-IV development environment.
SL has its own IDE and associated files/tables, when you "build/compile" a SL function it effectively translates&copies the SL code into the Pro-IV dev environment.
(Some of the SL tables may be referenced at Run time???)

If your functions exist at a SL level then DO NOT edit the functions using Pro-IV @MOD/@MODX as these changes will not be reflected at the SL level and therefore any changes at Pro-IV level will be lost when/if the function is subsequently edited at SL level. It is possible to have a system that combines both SL functions (which created PRO-IV function) with PRO-IV functions that have no SL equivalent.

My recollection is that SL was a better Dev Env than the Pro-IV Dev Env.

If you are new to Pro-IV then see/search earlier posts -



I think that understanding the Timing Cycle of the different function types S/R/U is key to learning Pro-IV

Hope this helps
