HP 48G - Command INDEX

: How much free memory does my calculator have?
: UsellEM (see p. 9) to find out: EEEN
: What does the ) annunciator indicate?
: Alow battery (see p. 39) or past-due alarm (p. 31).
: My machine seems to gradually slow down. Why?
: It may need to clean up borrowed or fragmented
sections of memory. Use (ON{C) (see p. 39) to do
a cleanup. (This clears the stack and PICT.)

Qo : Why do | get mixed units in the Equation Library
Solver even when | specify IZiIR or IEIIR 2
A: The Solver initializes only variables that don't al-
ready exist in the current directory. For unit con-
sistency, at the equation list in Equation Library,
press Il before selecting units.
Q: How do turn off the HALT annunciator?
A: UseKILL (see p. 54): FranxT) TN CAMW.
CommAND INDEX
The following Command Index lists all commands
(programmable objects) available in the HP 48G/GX.
It does not list operations, (non-programmable key-
board procedures); it's a programmer’s memory-jog-
ger. This booklet does not attempt to teach program-
ming. That topic is large enough to merit at least one
full-length book (see the inside back cover).
Each command name is accompanied by a brief(nay,
terse) description and its keyboard access, if any.*
Then opposite each command is a stack representa-
tion of its inputs and outputs. Object types are repre-
sented by surrounding delimiters, descriptive phrases,
and/or by variable naming conventions (i.e. x, y, and
other italicized names indicate real values; n and m
stand for integers, z is a complex number; etc.).
Not all possible object types are given—only the most
common. Often you can also use names or algebraic
expressions that evaluate to required types/values.
Not all error responses or flag dependencies are giv-
en (see pp. 78-80 for descriptions of system flags).
*If you do extensive programming and need to study certain commands
more thoroughly, you will find the HP 48G Series Advanced User’s Ref-
erence Manual from Hewlett-Packard to be very helpful.
