From the command-line
=====================
LEN=`echo "1ドル\c" | wc -c`
echo "033円&f0k${LEN}D${1}\c" # set title bar name
echo "033円&f-1k${LEN}D${1}\c" # set icon name
You can stick the following lines in your .profile or .kshrc to display
the system name and current directory in your hpterm title bar & icon:
if [ "$TERM" = hpterm ]; then
 alias cd=Hcd
 Hcd ()
 {
 if [ $# -ne 0 ]; then
 'cd' "$@"
 else
 'cd'
 fi
 NAME="$(uname -n):${PWD}"
 LEN=`echo "$NAME\c" | wc -c`
 # reset name of hpterm title bar & icon to $NAME
 echo "033円&f0k${LEN}D${NAME}\c" # set title bar name
 echo "033円&f-1k${LEN}D${NAME}\c" # set icon name
 }
 Hcd .
fi
Programmatically:
=================
Here's a two-line C program that'll do the trick:
/* Quick and dirty program to put argv[1] in the title bar of an hpterm
 Tom Arons, March 1992
*/
#include <string.h>
main(argc,argv)
int argc; char **argv;
{
 printf("033円&f0k%dD%s", strlen(argv[1]), argv[1]);
 printf("033円&f-1k%dD%s", strlen(argv[1]), argv[1]);
}
