HP 9g Graphing manual Before Using the Program Area, Program Control Instructions

Before Using the Program Area

Number of Remaining Steps: The program capacity is 400 steps. The number of steps indicates the amount of storage space available for programs, and it will decrease as programs are input. The number of remaining steps will also decrease when steps are converted to memories. See Array Variables above.

Program Type: You must specify in each program the calculation mode that the calculator should enter when executing the program. To perform binary, octal or hexadecimal calculations or conversions, choose BaseN; otherwise choose MAIN.

Program Area: There are 10 program areas for storing programs (P0–P9 ). If an area has a program stored in it, its number is displayed as a subscript (as in P1).

Program Control Instructions

The calculator’s programming language is similar to many programming languages, such as BASIC and C. You can access most of the programming commands from the program control instructions. You display these instructions by pressing [ 2nd ] [ INST ].
