Hi

I'd build an upper-level function:

myDEFAULT_color = color(155,120,60);
functionmystring(x,y,str,mycolor)//plots str on x, y in color mycolor. 
mycolor is optional//Default value for 
mycolorifargn(2)<4mycolor=myDEFAULT_colorendxstring(x,y,str)e=gce()e.font_foreground=mycolorendfunction


then use mystring instead of xstring
note that you may omit the last argument
