Hi,
Apart from Tore's usefull correct information there is also version() , if version(2) is returning 2 you are in development if version(2) returns 0 you are in Run time.
usufull if you want to have 2 different settings of your path depending on the version.
e.g.

Set Path To []
? SET('path')
*** Go ahead and set the path
If Version(2) # 0
	***  We are in Development Mode
	***  Set up Project search path
	m.lcPath = Home() + ';' + Fullpath( Curdir() ) + [Class;  Data; Forms; Images ; Menu; Progs ; Reports; ReportingFiles]

Else
	*** We are in Production Mode
	*** Set up application search paths
	m.lcPath = Fullpath( Curdir() ) + [ ;Reports ; ReportingFiles]
Endif

Stay healthy,
Koen
