Hi guys,

I once saw that you can set an empty string in the input, that is, without a name, and then the external variables when applied to the chart will be an empty string,

I had to use a blank string when I plotted the external variables on the chart.

Who remembers, knows?

Try setting the sinput

Vladimir Pastushak:

Try setting a sinput

Thanks, not it.

Better just an input string

I must have just imagined it :-(....

Separators in parameters:

enum ENUM_NOTHING {
   NOTHING // ===== ===== =====
};

sinput ENUM_NOTHING z_; // ===== Описание =====

Such a parameter will not affect the continuation of testing after stopping, because the user cannot accidentally change it.

that?

Taras Slobodyanik:

How do you make a non-breaking space?
