Memory and Storage
Memory Allocation
Data storage, in the form of registers, and program memory, in the
form of program lines, share a common memory space in the
HP-16C. This memory space consists of 203 bytes (eight bits to one
byte), all of which are initially* allocated to data storage. However,
as you enter program instructions (as explained in section 7,
Programming Basics) memory space is automatically allocated to
program memory. 203 Bytes

Converting Storage Registers to Program Memory
The automatic partitioning of memory space from data storage
into programming takes place in segments of seven bytes, each
segment worth seven program lines. Starting with the first line you
store in a program and continuing with each succeeding seventh
line, seven bytes (lines) of memory are converted from data storage
into program memory.
