Keyboard Commands versus Program Instructions
Not all functions operate the same in a program as they do when executed from the keyboard. Several examples are listed in this section. Other differences between the keyboard and program operation of a function are discussed in the chapters in which the functions are defined.
The HELP Function
From the keyboard, [ HELP ] displays the prompt SET NORMAL MODE? and a menu from which you can choose { YES }, { NO }, or { ESC }. If you press { YES }, the calculator resets the system parameters to their default settings. If you press { NO }, the calculator displays all parameters that are not set to their default condition and lets you choose between resetting the parameter or leaving it unchanged. Pressing { ESC } clears the menu.[ HELP ] as a program instruction resets the system parameters to their default settings and resets the partitions (excluding file space) to one-half data registers and one-half program memory. This is identical to pressing [ HELP ] { YES } from the keyboard.
The Status Function
From the keyboard, the [ LIST ] { ST } (status) function lists all parameters that are not already set to their default condition and displays the error number of the most recent error. { ST } as a program instruction places the number of the most recent error in the numeric display register. It does not list any status information.The QAD and CUB Functions
From the keyboard, the { QAD } and { CUB } selections of the [ FUNC ] menu prompt you to enter coefficients and display a message to identify the roots as real or complex.In a program, no prompts or messages appear. Instead, the { QAD } and { CUB } functions get coefficients from data registers 0, 1, 2, and 3. The results are stored in the same registers. For details, refer to this section of the RPD-95 User's Guide.
