>Has anyone used any tools for generating project metrics such as total line count for a project?

This simple thing counts rows in all prgs in one directory. It can easily be adapted to scan through a project and count the lines in each of the Methods memo of classes and forms, Tag fields of reports' and labels' dataenvironments, and thus count everything.

#define cr chr(13)+chr(10)
_cnt=0
_cnc=0
n=adir(a,"*.prg")
=asort(a)
for i= 1 to n
	m=filetostr(a[i,1])
	_x=occu(cr,m)
	_c=occu(cr+"*",m)
	? a(i,1), tran(_x, "999999") at 26, tran(_c, "999999") at 40
	_cnt=_cnt+_x
	_cnc=_cnc+_c
endf
? "Total",_cnt, "commented",_cnc
