Question regarding the "as" keyword in MetaEditor 5

[Johanny Perin Tankeu Tenembot]

Hello everyone,

I have a technical question that leaves me perplexed, and the official documentation has not been helpful.

I noticed that in MetaEditor 5 (latest version), the word "as" is highlighted in blue (like a reserved keyword) and appears in autocomplete suggestions.

However, my research shows that it is never mentioned as an official reserved keyword (unlike int, if or double).

I would like to understand its exact meaning and whether it is safe to use as a variable name, or if it has a hidden function that I should be aware of.

Thank you in advance for your help!

There is no “as” keyword. Without code, we can only guess.

"as" is indeed highlighted in MetaEditor, but is not mentioned in the documentation or in the MetaTrader 5 release notes.

Here's what I found in the release notes from October 26, 2018:

Added support for the inline, __inline and __forceinline specifiers when parsing code. The presence of the specifiers in the code causes no errors and does not affect the compilation. At the moment, this feature simplifies transferring С++ code to MQL5.

Perhaps "as" was added for some similar reason.

Furthermore, eight months ago, MetaQuotes' CEO announced that

The compiler will be able to work with Visual Studio projects and natively compile C/C++ projects to create MQL5 modules/libraries

"as" may have been added in preparation for this. But we can only guess.

In my personal opinion, this is a bad idea.

Yes there is an 'as' keyword.  It's used with resource.

#resource "Python/model.onnx" as uchar ExtModel[]

Given the information provided by Alain Verleyen, I must note that my answer, which I quote, is incorrect.
