Card Reader Operations
Here is the procedure for using [worax):
1.
2.
Ensure that the HP-41C is not in PRGM mode.
Using the following format, place a data control number into the
X-register.
bbb.eee
where: bbb is the beginning data storage register address;
eee is the ending data storage register address.
The calculator uses the absolute value of this number to control
which data storage registers are to be written to the data cards.
(The sign of the number in X is not altered, it is ignored.) The bbb
portion instructs the HP-41C to begin at that data storage register
address and the eee portion is the last data storage register to be
written. The bbb portion can be one to three digits and the eee
portion must be three digits.
For example, when using (worax], 10.020 would instruct the
calculator to write registers R, through R,to the card. If the eee
portion of the numberis less than or equal to bbb, the calculator
writes only the registers specified by bbb. So, the number 10.000
would write just Ry,.
If eee is larger than the number of currently existing registers, the
calculator writes from bbb to the last existing register (inclusive).
With the control number in the X-register, execute [worax]. In a
program, simply key the control number into the X-register (as a
line in the program), and follow it with the function.
The HP-41C will prompt you to insert a card with
RDY kk OF nn
where kk is the next track to be written and nn is the total number
of tracks required.
Select a blank, unclipped card and insert track 1 into the card
reader. The calculator now uses the control number to determine
which data storage registers are to be written onto the card.
The NONEXISTENT display indicates that the first register specified by
the control number does not currently exist (is not allocated).
