The 
 
DEMO_MODE function returns True if IDL is running in the timed demo mode (i.e., a license manager is not running). Calling this function causes a 
FLUSH, -1
 command to be issued.
 
This routine is written in the IDL language. Its source code can be found in the file 
demo_mode.pro
 in the 
lib
 subdirectory of the IDL distribution.
