Clock Functions
The following table describes the macro CALLs that you use to set and read the
clock.
wait_m1() Waits for the M1 file to be read. None None
wait_m0() Waits for the M0 file to be updated. None None
wait_input_image(%1) Waits on the input image file to be read. None %1 = The success
of the transfer:
0 = Not read yet
1 = Has been read
2 = Not supported
wait_output_image(%1) Waits for the SLC output image file to be
updated. None %1 = The success
of the transfer:
0 = Not read yet
1 = Has been read
2 = Not supported

Table A.4 Clock Macros
Clock Macro CALLs Macro Inputs Outputs
input_time() Asks the operator for the correct time, then sets the clock. No
input or output variables. None None
set_time(%1,%2,%3) Sets the clock to the time indicated by %1, %2, and %3. %1 = Hours (0 to 23)
%2 = Minutes (0 to 59)
%3 = seconds (0 to 59) None
set_date(%1,%2,%3) Sets the clock to the date indicated by %1, %2, and %3. %1 = Days (1 to 31)
%2 = Months (1 to 12)
%3 = Years (0 to 99) None
input_date() Sets the Wall Clock date. It asks the operator for the date,
and sets the clock. None None
set_day() Asks the operator for the day of week, and sets the Wall
Clock day of week. None None
get_time(%1,%2,%3) Reads the time from the clock and returns the time in the
variables %1, %2, and %3. None %1 = Hours
%2 = Minutes
%3 = Seconds
print_time() Reads the time from the clock and prints the time. The cursor
is left at the end of the time. (That is, no carriage return/line
feed is sent.) None None
print_date() Reads the date from the clock and prints the date. The cursor
is left at the end of the date. (That is, no carriage return/line
feed is sent.) None None
print_day() Reads the day from the clock and prints the day. The cursor is
left at the end of the day. (That is, no carriage return/line feed
is sent.) None None
