EL - variable signal names

[Peter Ryan <pryan@xxxxxxxxxxxxxx>]

Does anybody know of some way of programmatically setting the signal value

ie. in the statement:  
	Buy ("signal") at close;

is there any way of having a variable instead of the hard-coded literal.

I run several versions of the same system (with different input values), and am looking for some way of recognising which system is listing in the STCC window.

Thanks in advance
