Andreas,
The NAME of the parameter is used to IDENTIFY this parameter.
It is like a variable NAME in the code. Variable name has to be fixed because it is
used to IDENTIFY it.
It can not change because then you won't have one but hundreds/thousands parameters
if you scanned through your entire database.
It is beyond me why you would want to implement such weirdness.
Isn't it just better / easier and obvious to write:
CompareTicker = ParamStr( "Compare with:", CompareTickerDefault );
You know what the current ticker is ! It is displayed in the CAPTION of the chart window
so there is NO reason to display it again in the parameter window other than
WASTING display space for repeating the information that is already there.
So my answer is *NO*. I won't implement such useless functionality.
Best regards,
Tomasz Janeczko
