Program line 000 and the GTO 000 instruction:
The GTO 000 instruction tells the calculator to go to and execute program line
000. Line 000 contains no regular instruction, but holds a default instruction
that tells the calculator to stop execution of the program. This means after you
run the program, the calculator goes to program line 000 and stops, waiting for
you to enter new data and run the program again. The calculator is also set to
program line 000 when b., P/R is touched, or by touching b PRGM in run
mode. The GTO 000 instruction is stored in every program line before
beginning the program and is replaced by the instructions entered and moved
into the next program line, all the way up to the 400
th
(maximum) program line.
The calculator is set to hold eight lines of program memory, so if you had eight
lines of programming, the calculator would automatically perform instruction
GTO 000 after the eighth line was performed. Entering more that eight lines
automatically expands to hold the additional instructions and program lines.
To find how many program lines (including r GTO 000) are in program
memory, touch r MEM to prompt the display below where xx stands for the
number of allocated program lines and yy stands for the number of available
registers:
P-xx r-yy
Performing a Program One Line at a Time
SST allows you to run a program a single step at a time and check that the
program you wrote matches the program you stored. This does not mean that
the program you wrote will correctly calculate your results. (Even skilled
programmers’ programs don’t run correctly at first.)
