Equation Writer File Manager EDIT Opens the selected component in the command line editor. Make your changes, then press \ to return to Equation Writer. CURS Enables cursor mode. Use the arrow keys to enclose the part of the equation that you want to select in a box, then press \ to return to selection mode, with the boxed component selected. BIG Toggles Equation Writer between standard font and mini-font. EVAL Evaluates the selection. Equivalent to pressing >ù. FACTO Applies the FACTOR command to the selection. TEXPA Applies the TEXPAND command to the selection. EDIT Opens the selected object. If the object can be edited, it is opened in the command line editor. COPY Copies the selected object. After you press COPY, select the destination directory, and press OK to paste the object. MOVE Moves the selected object. After you press move, select the destination directory, and press OK to move the object to the directory. RCL Copies the selected object to the command line. EVAL Evaluates the selected object. TREE Returns to the File Manager opening screen, showing the ports and the HOME directory. PURGE Deletes the selected object or objects. RENAM Renames an object. The calculator prompts for a new name for the selected object. NEW Opens the New Variable input form, used to create a new variable or directory. ORDER When you select multiple objects (using \) places the selected objects in the order in which you selected them. SEND Sends the selected object or objects to another calculator. RECV Receives objects sent from another calculator. HALT Suspends your File Manager session. You can return to the session by pressing <;. VIEW Displays the contents of the currently selected object. You cannot edit the contents. EDITB Opens the currently selected object in the most suitable editor. HEADE Toggles the File Manager header between memory and selection details, and path and content details. LIST Hides or shows the details of listed objects.  Continued 4 Stack Matrix Writer ECHO Press ECHO, then \ to copy the contents of the current level to the command line. Edit the contents on the command line, and press \ to place them on level 1 of the stack. VIEW Displays the contents of the current level in textbook mode. EDIT Opens the contents of the current level in the most appropriate editor, ready for editing. INFO Displays information about the object at the current level, including its size in bytes. PICK Copies the contents of the current level to stack level 1. All existing objects are pushed up one level. ROLL Moves the contents of the current level to level 1. The portion of the stack below the current level is rolled up. ROLLD Moves the contents of level 1 to the current level. The portion of the stack beneath the current level is rolled down. →LIST Creates a list that contains the stack objects from 1 to the current level. The newly created list is placed on level 1 of the stack, and the original objects are removed. DUPN Duplicates the levels from the currently selected level to level 1, and pushes up the existing levels to accommodate the duplicated levels. DROPN Deletes all levels below the selected level. KEEP Deletes all levels above the selected level. GOTO Prompts for a stack level to select, then selects the level number that you enter. LEVEL Copies the current level number to level 1 of the stack. EDIT Places the contents of the currently selected cell on the command line, ready for editing. VEC For single-row matrices, sets that the row of values is a vector rather than a matrix. That is, when you place it on the command line, it is enclosed in a single pair of square brackets rather than two pairs. ←WID Reduces the width of the columns. WID→ Increases the width of the columns. GO→ Sets that the cursor moves to the left by default when you enter data. GO↓ Sets that the cursor moves down by default when you enter data. +ROW Adds a row filled with zeros at the cursor position –ROW Deletes the row at the cursor position. +COL Adds a column filled with zeros at the cursor position. –COL Deletes the column at the cursor position. →STK Copies the selected element only to the stack or the command line. GOTO Displays an input form that allows you to specify the column and row coordinates to select. DEL Fills a selected range with zeros. 5 Graphics Editor DOT+ Turns on pixels beneath the cursor. DOT– Turns off pixels beneath the cursor. LINE Draws a line from a marked point to the cursor. (PressŒ or MARK to mark a point). TLINE Same as LINE but toggles pixels on or off. BOX Draws a rectangle from a marked point to the cursor. CIRCL Draws a circle around a marked point with a radius indicated by the position of the cursor. MARK Marks a point. Same as pressing Œ. +/– Inverts the cursor when it crosses an object. LABEL Displays axes labels. DEL Deletes that part of the graphic bounded by a rectangle from a marked point to the cursor. ERASE Erases the entire graphic. MENU Hides the function-key menu. (Press f, =, or Š to redisplay the menu.) SUB Copies to the stack that part of the graphic bounded by the rectangle from a marked point to the cursor REPL Pastes what was last copied with SUB. PICT→ Copies the graphic to the stack. X,Y→ Copies the cursor coordinates to the stack. PICT Replaces the edit menu with the picture menu. 6 Reserved Names and Constants You should avoid using certain names for variables, because their contents are interpreted by the calculator in set ways. Some examples are given in the following table. Name Use 0DETYPE The differential equation type used in the DESOLVE command. ALRMDAT Data for current alarms. CST Current contents of a custom menu. d# Indicates a user-defined derivative, where # is the number of the defined derivative. EPS The smallest real value below which the calculator rounds to zero for some operations, for example EPSX0. EQ Current equation, plotting and numeric solving. ERABLEMSG Information relating to unevaluated integrations. EXITED If this variable contains a program, the program runs whenever the command line editor session is ended. EXPR Current expression, symbolic operations. IERR Uncertainty in current integration. IOPAR Current parameters for I/O operations. MODULO The value of the current modulo setting. n1, n2, Integer coefficients used by ISOL. PPAR Current parameters for plotting. PRTPAR Current parameters for printing. s1, s2, Sign coefficients used by ISOL and QUAD. ΣDAT Current matrix of data used for statistics. ΣPAR Parameters for statistics calculations. PRIMIT The last computed antiderivative. REALASUME A list of variables that the computer algebra system assumes are real values. STARTED If this variable contains a program, the program runs whenever the command line editor session is started with EDIT EDITB, VISIT, VISITB, or ] in RPN mode. STARTERR Used to customize error message displays. STARTEQW Used to apply a customized operation to a selected component in Equation Writer. STARTOFF If this variable contains a program, the program runs whenever the calculator turns off automatically. STARTUP If this variable contains a program, the program runs after a warm start. TOFF Sets the number of ticks before the calculator automatically turns off. TPAR Current parameters for viewing tables. VPAR Current parameters for viewing 3-D plots. VX The default variable used in symbolic operations. ZPAR Zoom parameters in plotting.  7 Units A unit object is comprised of a number and a unit separated by the underscore character. An example is 3_ ft/s. You can use the HP 49G to convert unit objects from one unit to another, comparable, unit. You can also use unit objects in calculations. The following table lists all the units you can use to create unit objects, grouped according uploads/Litterature/ hp49g-pocket-guide.pdf
