memory. For example, filling the first 70 lines and then keying a
command into line 71 converts register Rg to 7 more lines of
program memory (lines 71-77), and so on.
Note: Your HP-11C converts storage registers to program
lines in reverse numerical order, from Rg to Ry and then
from Rg to Rq. For this reason it is good practice to program
your and operations using data registers in the
opposite order; that is, beginning with register Ry. This
procedure helps avoid accidentally programming and
(RCL]for data registers which have been converted to lines of
program memory. Remember also that the calculator does
not retain data previously stored in registers that are later
converted to lines of program memory.
Converting Program Memory to
Storage Registers
Pressing CLEAR in Program mode converts all shared
program memory (lines 064-203) to storage registers R, through
R g. However, deleting individual lines of program memory allows
you to convert portions of shared memory to storage registers
without clearing all of program memory. (Refer to page 105,
Deleting Instructions.)
Using [MEM]
The [MEM] (memory) function on your calculator describes the
current memory allocation in or out of program mode. For example,
if you press (MEM] with 44 lines of program memory occupied,
you will see the following display:
T
Lines remaining to be occupied The next storage register to be
before the calculator automati- converted.
cally converts a storage register
to 7 more program lines.
