HP HP-11C User Manual

76 Section 5: Programming Basics
As instructions are keyed into program memory, they are stored
sequentially in the available space. If all 63 lines of the initial
program space are already occupied and you key in a 64*? program
instruction, data storage register R gis automatically reallocated to
seven more lines of program memory to make room for the new
instruction (plus up to six more). The HP-11C’s memory
configuration would then be 70 lines of program memory and 20
data storage registers. Keying in a 71% program instruction
automatically reallocates storage register R g to seven additional
lines of program memory. This pattern can be repeated until all 20
convertible data storage register (R g through R, Rg through Ry)
have been reallocated to program memory.
If all convertible data storage registers are reallocated to program
memory, the memory configuration will be 203 program lines and
one data storage register (the Index—R;—register). The following
table shows the allocation of the lines of program memory to their
respective storage registers.
Ry 064—070 Ry 134—140
Rg 071—077 Rg 141—147

Storage Register/Program Memory Allocation
Deleting lines of program memory one by one from any location in
program memory causes the calculator to automatically reallocate
