PROGRAM DESCRIPTION
The program (PRGM) key places the HP 41C/CV into the programming mode. Keystrokes are recorded
as programming instructions. The PRGM annunciator appears in the display.
The GTO key places the HP 41C/CV at the end of program memory and inserts the END instruction if
it is not present. The HP 41C/CV displays the number of registers left in program memory.
The Label (LBL) key labels the program with the name "IN184". The ALPHA key toggles the HP 41C/CV
into and out of ALPHA mode to enter letters in the program name. Press the gold shift key before key-
ing each number.
The Execute (XEQ) command followed by the Auto input/output (AUTOIO) command, sets up the
loop so the interface automatically searches for the proper device to carry out the operations of
the program.
Flag 17 is cleared. Flag 17 controls how the HP-IL moduel uses the standard end-of-line indicator; Car-
riage Return (CR) and Line Feed (LF).
The name of the device the interface will search for is entered here.
The Execute (XEQ) command followed by the Find Identity (FINDID) command causes the interface
to search for the HP 5384A and determine the address of the device on the loop.
The command codes that cause the counter to make the Frequency A measurement, set the gate time
to one second and enable the 100 KHz low pass filter are entered into the ALPHA register.
The Execute (XEQ) command followed by the Output A (OUTA) command causes the contents of the
ALPHA register to be sent to the counter.
The Execute (XEQ) command followed by the Input Decimal (IND) command causes the counter dis-
play (X register) of the HP 41C/CV.
The GTO command places an END statement at the end of the program. The display will show how
many registers are left in program memory.
The program (PRGM) key toggles the HP 41C/CV out of the program mode.
The Assign (ASN) key will assign the program "IN184" to a key location on the HP 41C/CV keyboard .
The LN key is the key location selected for the program "IN184". The assigned key location 1, 5, (Row
1, Column 5) is briefly displayed at the right side of the display.
The USER key toggles the HP 41C/CV into the USER mode for access to the programs called up by the
various key locations.
The LN key in the USER mode executes the program "IN184". Program execution is indicated by a
~-
symbol moving across the display from left to right.
