Mike Nolan posted a shell script to modify the date and time on an NCR 4940
terminal and asked for refinements.
We currently use this C program to perform this function on our NCR 32/650
under 02.01.01:
/* Courtesy of Northwest Analytical, Portland, Oregon */
#include <time.h>
main ()
{
long tod; /* Time of day in seconds */
struct tm *ct; /* Time fields */
time(&tod);
ct = localtime(&tod);
printf("\033\001\015%02d\016%02d\017%02d",
ct->tm_mday, ct->tm_mon+1, ct->tm_year);
printf("\025%02d\026%02d\037", ct->tm_min, ct->tm_hour);
}
Also, here's a short shell script by Joel Barton, Oregon Department of
Agriculture, that will also do the job:
set `date '+%d %m %y %M %H'`
echo "^[^A^M$1^N$2^O$319^U$4^V$5^_"
The ^'s represent a CTRL v typed in vi. Also, the $319 will need to be
changed to $320 for the 21st century.

Control characters can be handled by echo in much the same way as in C: echo "\033\001\r$1\016$2\017$319\025$4\026$5\037" or even better, avoid the echo altogether: date "+^[^A^M%d^N%m^O%y19^U%M^V%H^_" -- -Mike Wescott mike.wescott@ncrcae.Columbia.NCR.COM
