TIME
gives the date and time in the form
TIME Sun Dec 29 17:51:17 1985
on the current (TIME) line. TIME is useful in time measurement for long
sequences of Survo operations activated by PREFIX ESC.

Sucro /TDIFF (without parameters) gives the difference of two preceding
TIME results in seconds.

TIME COUNT START (without parameters) resets a clock to 0.000 seconds.
TIME COUNT END   (without parameters) gives the time elapsed since the
last activation of TIME COUNT START.


For measuring execution times of various Survo operations
in series of activations (e.g. in sucros) the following form
of TIME COUNT is useful.

TIME COUNT FILE <pathname_of_a_text_file> 
opens a new text file for saving execution times.
When an operation has been activated and completed, the time elapsed
is saved in the text file as a new line in the form
<name_of_command> <execution_time_in_seconds> 
Example: MNSIMUL 4.840
         --- 2.010
         CORR 1.230

Times between activations (typing text and commands, moving the cursor,
etc.) are indicated in the file by '--- commands'.
Before studying and analyzing the contents of the text file it must be
closed by the command
TIME COUNT FILE CLOSE
