Introduction
Inthis Reference Guide youwill findthe following information:
•CATALOG, Strings, Hyperbolic Functions - Includes instructions onbrowsing, using, entering strings, andotherfunctions inthe CATALOG.
•Commands andFunctions Listing - Includes an alphabetical listing of all CATALOG items, referencing:
-FunctionorInstruction/Arguments
-Results
-KeyorKeys/MenuorScreen/Item
•Arithmetic Operations, Test Relations, andSymbols - Items whose names are not alphabetic (suchas +, !, and>).
•ErrorMessages - Includes a listing of errortypes withpossible causes and suggestedremedies.
2 Introduction
CATALOG, Strings, Hyperbolic Functions
What Is theCATALOG?
The CATALOG is analphabetical list of all functions andinstructions onthe
TI-84 Plus CE. Youalsocanaccess eachCATALOG item from a menuorthe keyboard, except:
•The sixstring functions
•The sixhyperbolic functions
•The solve( instructionwithout the equationsolvereditor
•The inferential stat functions without the inferential stat editors
Note: The onlyCATALOG programming commands youcanexecute from the home screenare GetCalc(, Get(, and Send(.

Browsing theTI-84 Plus CE Catalog
Selecting anItem from the CATALOG
Tobrowse andselect a CATALOG item, follow these steps. 1. Press y Ntodisplaythe CATALOG.
The 4 inthe first columnis the selectioncursor.
2.Press † or } toscroll the CATALOG until the selectioncursorpoints tothe item youwant.
•Tojumptothe first item beginning witha particularletter, press that letter; alpha-lockis on.
•Items that beginwitha numberare inalphabetical orderaccording tothe first letterafterthe number. Forexample, 2-PropZTest( is among the items that beginwiththe letter P.
•Functions that appearas symbols, suchas +, L1, <, and $(, follow the last item that begins with Z. Tojumptothe first symbol, !, press [q].
3.Press Í topaste the item tothe current screen.
Note:
•From the topof the CATALOG menu, press } tomove tothe bottom. From the bottom, press † tomove tothe top.
•WhenyourTI-84 Plus CE is inMathPrint™mode, manyfunctions will paste the MathPrint™template onthe home screen. Forexample, abs( pastes the absolute value template onthe home screeninsteadof abs(.

Using Catalog Help
Displaying Catalog Help
YoucandisplayCatalog Helparguments forfunctions intwoways:
•Using analpha/numeric functionlisting inthe catalog (e.g, y N).
•Using the functions listedincertainmenus (e.g, »).
Catalog Help lists the valid arguments for the function under the edit line. Arguments in brackets are optional.
1.Displaythe menuthat contains the function.
2.Use } and/or † tomove the cursortothe function.
3.Press Ãtodisplayarguments forthe function. The cursoris onthe functionedit line.
Note:
•The catalog (y N) is displayedinalphabetical order. Whenyoudisplaythe catalog, the alpha-lockis turnedon. Press the first letterof the functionname to skipfunctionnames that come before it alphabetically. Use } and/or † tomove the cursortothe function.
•Not all catalog functions have associatedarguments. If the functiondoes not require anargument, Catalog Helpdisplays the message “Noarguments required forthis item.”
Catalog HelpCommands
•Select MORE (if available) todisplaymore arguments forthe function.
6 CATALOG,Strings,HyperbolicFunctions
•Use shortcut menus ƒ^ through a throughforargument values if available.
•Enteryourargument values onthe functionedit line, andthenselect PASTE to paste the functionandthe argument values youentered.
Note:Youcanpaste tomost cursorlocations.
•Select ESC toexit the Catalog Helpscreen.

Entering and Using Strings
WhatIs a String?
A string is a sequence of characters that youenclose withinquotationmarks. Onthe TI-84 Plus CE, a string has twoprimaryapplications.
•It defines text tobe displayedina program.
•It accepts input from the keyboardina program. Characters are the units that youcombine toform a string.
•Eachnumber, letter, andspace counts as one character.
•Eachinstructionorfunctionname, suchas sin( or cos(, counts as one character;the TI-84 Plus CE interprets eachinstructionorfunctionname as one character.
Entering a String
Toentera string ona blankline onthe home screenorina program, follow these steps.
1.Press ƒW toindicate the beginning of the string.
2.Enterthe characters that comprise the string.
•Use anycombinationof numbers, letters, functionnames, orinstructionnames tocreate the string.
•Toentera blankspace, press ƒO.
•Toenterseveral alpha characters ina row, press ƒ7toactivate alphalock.
3.Press ƒW toindicate the endof the string.
ãstringã
4.Press Í. Onthe home screen, the string is displayedonthe next line without quotations. Anellipsis (...) indicates that the string continues beyondthe screen. To scroll tosee the entire string, press ~ and |.
Note: A string must be enclosedinquotationmarks. The quotationmarks donot count as string characters.
8 CATALOG,Strings,HyperbolicFunctions
Storing Strings to String Variables
String Variables
The TI-84 Plus CE, has 10 variables towhichyoucanstore strings. Youcanuse string variables withstring functions andinstructions.
Todisplaythe VARSSTRING menu, follow these steps.
1. Press ½ todisplaythe VARS menu. Move the cursorto 7:String.
2. Press Í todisplaythe STRING secondarymenu.
Storing a String toa String Variable
Tostore a string toa string variable, follow these steps.
1.Press ƒW, enterthe string, andpress ƒW.
2.Press ¿.
3.Press ½ 7 todisplaythe VARSSTRING menu.
4.Select the string variable (from Str1 to Str9, or Str0) towhichyouwant tostore the string.
CATALOG,Strings,HyperbolicFunctions 9
The string variable is pastedtothe current cursorlocation, next tothe store symbol (!).
5.Press Í tostore the string tothe string variable. Onthe home screen, the storedstring is displayedonthe next line without quotationmarks.
Displaying the Contents of a String Variable
Todisplaythe contents of a string variable onthe home screen, select the string variable from the VARSSTRING menu, andthenpress Í. The string is displayed.

Commandsand FunctionsListing
The purpose of this table of informationis toprovide a short descriptionwithsyntaxof commandarguments as appropriate andmenulocations foreachcommandor functioninthe Catalog listing inthe calculator.
This table is useful forexecuting commands whenusing the calculatororcreating TIBasic programs.
Items whose names are not alphabetic (suchas +, !, and>) are listedinthe Arithmetic Operations, Test Relations, andSymbols section. Unless otherwise specified, all examples inthis sectionwere performedinthe default reset mode, andall variables are assumedtobe the default value of 0.
From the CATALOG, youcanpaste anyfunctionorcommandtothe home screenortoa commandline inthe program editor.
The same syntaxinformationforfunctionandcommandarguments below is available onthe calculatorandalsointhe TI Connect™CE Program Editor.
•Onthe calculator, pressing [+] whena functionorcommandis highlightedinthe menulisting will displaythe Catalog Helpsyntaxeditortoassist yourentries.
•Using TI Connect™CE Program Editor, the catalog listing alsodisplays the syntaxof the arguments forfunctions andcommands.
Note that some functions andcommands are onlyvalidwhenexecutedina TI-Basic program andnot from the home screen.
The items inthis table appearinthe same orderas theyappearinthe CATALOG (y [catalog].)
Inthe table below, the † symbol indicates eitherkeystrokes orcertaincommands whichare onlyavailable inthe Program Editormode onthe calculator. Press ¼ and select to EDIT anexisting program or NEW tostart a new program toset the calculator inthe Program Edit mode.
Some arguments are optional. Optional arguments will be indicatedwithin [ ] inthe syntaxhelpgiveninthe table below. [ ] are not symbols onthe calculatorandare not tobe typedin. Theyare usedhere onlytoindicate anoptional argument.
Onthe calculator, functions andcommands paste as "tokens." This means theypaste as one characterandnot as individual letters, symbols andspaces. Donot attempt to type inanyfunctionorcommandonthe calculator. Just paste the tokenfrom menu locations. Watchthe cursorjumpovertokens as youedit toget a betterunderstanding of tokens.
InTI Connect™CE Program Editor, youcan"feel" the same experience of pasting tokens whenusing the Catalog tree providedinthat editor. Youalsocantype inthe functions andcommands if youknow the correct format andsyntax. TI Connect™CE "tokenizes" the functions andcommands whenyousendthe program tothe calculator. However, youmust type inthe functions andcommands exactlyas the tokens. Note that some commands will have spaces as part of the tokenwhichyoumight not see. For example, Pause commandas a tokenhas a space at the end. Once yousendthe
