HP HP-28S User Manual

If the cursor is positioned at the end of the command line, or if Insert
mode is active, spaces are included as needed to keep successive com-
mands separate.
Exceptions
To enable you to select a mode while using the command line in Im-
mediate or Algebraic entry mode, the following command keys
execute
their command without disturbing the command line.
• STO , OEG ,and RAD in the MODE menu.
• DEC , HEX , OCT ,and BIN in the BINARY menu.
Since the following commands make sense only in a program, press-
ing one of these keys always writes the command's name in the
command line.
• HALT in the PROGRAM CONTROL menu.
• All keys in the PROGRAM BRANCH menu.
To help prevent the accidental loss of variables, pressing CLUSR (in
the MEMORY menu) always writes CLUSR in the command line. You
must then press I ENTER I to execute the command.
