Underscore support in variable, macro, function definitions

[ffeppon]

Dear developpers,

Is there any reason why the underscore is not allowed in variable definitions?

real var_1=0;

results in

syntax error current line = 1 Compile error : syntax error line number :1, error Compile error : syntax error line number :1,

Sometime it is nice to have underscores in variables name for readability.

Thanks

The underscore character is not allowed in the EDP scripts (see the doc)

It will be used in the future as an operator for time derivatives, for example

It makes sense!

Thank you.

yes, but I reserved _ for other thing,

Best Regards,

Frédéric Hecht.
