R GRAMIMI
The Hewlett Packard Model 9100A has a maximum capa-
c tty of 196 program steps. The 0, 1, 2, 3, 4, 5, 6, 7, 8,
9, a, b c, and d regtsters can be used for etther program
or data storage. The X, Y and Z regtsters are the display
regtsters and the e and F regtsters are only data storage
regtster~. these ftve regtsters cannot be used for program
storage.
Program stor age conststs of a 14 by 14 array (see Figure
1 ). The regtsters are destgnated 0, 1, 2, 3, 4, 5, 6, 7, 8,
9,
a, b, c, and d as are the characters in each register.
Memot"Y address c2 ind1cates the c regtster and character
2 tn the c regtster.
A program ts stored so that the regtster with the starting
addres.s of the program ts ftlled w1th the program steps be-
fore the next sequenttal regtster ts entered to store pro-
gram steps. Wtth the first program step in location 00,
program storage wtll be used tn the followtng manner: 00,
01, ... 09. Oa. Ob, Oe, Od. 10 .... 19, la, 1b, lc, ld,
20 ... up to dc , d d. th e address at which the program
coql;lter resets to 00.
lt ts not necessary to learn a program language for the
Calculator. Keyboard operations are the program instruc-
tlons.
Each program step is one keyboard instruction.
Programs
that require more storage than th e e and f regis-
ters necess1tate use of a register that could be used for
program storage. A complete reg1ster is required for
stonng a ten-dtgtt number and the two-digit exponent;
therefore.
the maxtmum program stze of 196 steps is re-
duced by 14 steps for each program register used for data
