Units
A unit object is comprised of a number and a unit separated
by the underscore character. An example is 3_ ft/s. You can
use the HP 49G to convert unit objects from one unit to
another, comparable, unit. You can also use unit objects in
calculations. The following table lists all the units you can use
to create unit objects, grouped according to their category.
You choose a category—and a unit—by first pressing
>ø . (Unit abbreviations are described in the User’s
Guide .)

Error and Status Messages
Errors during an operation or program execution generally
cause the operation or program to abort and a message to
appear.
The HP 49G enables you to detect and trap errors during
program execution via the IFERR command. To identify the
error after it has occurred, use the ERRN command to get its
number, or ERRM to get its message.
You can also cause an error to occur in a program, via
DOERR( n ), where n is the error number of the desired error
(see the table below). You can cause a customized error to
occur, via DOERR(" message "), where message is a
character string of your choice.
The following table lists both error messages and status
messages. These are sorted into categories

System Operations
For system operations, you press and hold the ; key, then
press and release certain other keys before releasing ; .
System Flags
Flags are mode settings and mode indicators. To see a list of
system flags, press h FLAGS.
Many flags can be set and cleared from input forms (such as

and others). You can also set, clear, or test a flag, by
specifying the flag number as the argument in a flag
command (SF, CF, FS?, etc).
Keys Operation
;af Cold restart. Erases home and port 0 memory
and resets the calculator’s default settings.
;b Cancels keystroke (prior to key release).
;c Warm restart. Preserves memory.
;d Starts interactive self-test.
;e Starts continuous self-test.
;[ Sends screen dump to the serial port.

Object Types
The HP 49G makes use of 30 types of objects (listed in the
table below). Commands relevant to object types are:
• TYPE( obj ) Returns the object’s type.
•VTYPE(' name ') Returns the named object’s type.
•TVARS( type ) Lists all objects of the specified type in the
current directory.
• VARS Lists all objects in the current directory.

internal number and the key or combination of keys that
display the character. (An ampersand denotes that you hold
down the first key while you press the second key). You can
also display a character using the Characters tool ( > chars).

Command Reference
All the HP 49G commands are listed in the table commencing
on page 21. A brief description of each command is provided,
together with the key or keys that provide access to the
command. Where appropriate, at least one argument (input)
and the corresponding result (output) is provided. In many
cases, a command can take many more types of argument.
To se a full listing of the arguments applicable to each
command, see the Advanced User ’ s Guide .
The commands are listed alphabetically. Commands referred
to solely by a non-alphabetic character—for example,%—are
listed after those referred to by alphabetic characters. Where
a non-alphabetic character is the first character—for example,
→DIAG—the command is sorted as if the character did not
exist. In other cases where a command name includes a non-
alphabetic character—for example, I→Rand DIAG→—the
non-alphabetic character is treated as ‘Z’ in sorting the
commands.
The commands that are functions are indicated by an asterisk
at the end of the command description. (You can include
functions in an algebraic expression.)
The codes and abbreviations used to represent the inputs
and outputs are set out in the following table.
In algebraic mode, the order that the inputs are listed is the
same as the order in which you must specify the arguments.
Similarly, the outputs are listed in the order in which they are
returned.
In RPN mode, the last input is what should be on level 1 prior
to executing the command, the second last input is what
should be on level 2, the third last on level 3, and so on.
Similarly, the last output appears on level 1, the second last
appears on level 2, and so on.
