Very basic, when use # ? (M language)

[kimalto452]

Hi, I read documentation but can't find explanation for what mean # and when I need to use it. I se its use for variable name with space... but I saw more this symbol in code something like #date() I suspect what its use for data type... but I can't find some explanation, can you help me with some link to doc or some explanation?

Hi @kimalto452 ,

unfortunatels this is used in too many different ways.

You can read more about its role as an escape sign and part of identifiers here: https://docs.microsoft.com/en-us/powerquery-m/m-spec-lexical-structure

But they are also using it in some function names, which I find very unfortunate as well. Documentation about this can only be found in the function documentation itself: https://docs.microsoft.com/en-us/powerquery-m/sharptable
