E-109 4. Use e and d to mov e the cursor around the program, and perform the required operations to edit the contents of the program or to add ne w contents. • Y ou can press 1 f to jump to the beginning of the program, while 1 c jumps to the end. 5.
E-110 Pressing J will display the prog ram editing screen, with the cursor located at the point where ex ecution was interrupted. A Using the Prog Command to Run a Pr ogram The Prog command can be used to specify a program fi le name and run that program directly from the COMP Mode or BASE-N Mode.
E-111 Note The mode that the calculator will enter automatically when you clear an error message depends on the program’ s r un mode, as sho wn below .
E-112 A Adding a File Name to “Fa vorites” Y ou can add the fi le name of an often-used program to “F avorites”, which will cause the name to be display ed at the top of the fi le screens. Operation Procedure 1. On a fi le screen, highlight the name of the fi le y ou want to add to “F avorites”.
E-113 To delete a program with this run mode: Display this screen: COMP or BASE-N Prog Delete fi le menu Fo rm ula Fmla Delete fi le menu 3. Use c and f to mov e the highlighting to the name of the program you want to delete and then press E . • This will cause the “Delete File?” confi rmation message to appear.
E-114 Example ? → A : A 2 : Ans 2 ^ (Output Command) ( 1 x ) Syntax <statement> ^ <statement> Function P auses program e xecution and displa ys the result of the current ex ecution. The Q symbol is turned on while program ex ecution is paused by this command.
E-115 Note These commands evaluate the e xpressions on either side, and return 1 if true and 0 if false. A Jump Commands Goto ~ Lbl Syntax Goto n : .... : Lbl n or Lbl n : .... : Goto n ( n is an integer from 0 to 9, or a var iable name from A through Z.
E-116 Example Lbl 1 : ? → A : A > 0 S ' (A) ^ Goto 1 A Control Structure Commands: If Statements The If statement is used to control program e xecution branching according to whether the expression f ollowing If (which is the branching condition) is true or f alse.

Subroutines Main Routine Lev el 1 Lev el 2 Lev el 3 Lev el 4 • A subroutine can be called up as many times as y ou like from the main routine. A subroutine can be called up from any number of main routines.
E-119 Return (COMP) Syntax ... : Return : ... Function Returns from a subroutine to the program from the program that called the subroutine. In a main routine, this command ter minates the progr am.

E-122 Important! List X, List Y , and List Freq correspond respectiv ely to the X-column, Y -column, and the FREQ-column of the ST A T Mode’ s ST A T editor screen. Function The List command is used in combination with X ( S 0 ), Y ( S . ), F req ( z – {ST A T} 1 (LIST) 2 ) to perform the operations described in parentheses, abov e.
