What are the limitations of custom mql code boxes?

[LightMasterSunrise]

I have found source code for a GRNN (Generalized Regression Neural Network) I would like to use it within fxdreema, but I know I cant use it as is because the file is mqh (library file) and if I am not mistaken, fxdreema does not support importing via #include property. However, I was thinking, I could reconstruct it so that the GRNN would be native to my current ea build by switching the void parameters using the custom mql code boxes, but before I undertake this journey, I would like to know the limitations of these custom mql code boxes, otherwise I may try to build one from scratch within fxdreema, if I can wrap my brain around arrays and if I find a way to make matrices. I thought it would be a great idea to implement having a template that I can easily plug and play right within fx dreema, with all the indicators I so choose, without needing to program it all.

Wow, this is advanced programming. Probably roar can tell something about this, but I'm not sure. I hope he can take a look at this.
