	Introduction: Why GLUE? GLUE features What is GLUE good for? Installing GLUE Getting started: Some simple examples The power of GLUE: A more advanced example The GLUE language Comments Symbols Constants String constants Numeric constants Nil constant define statement Variables Expressions Operators Unary Operators Binary Operators Ternary Operators Operator precedence Function calls Method calls Statements Simple statement If statement Switch statement Select statement For statement While statement Do statement Break statement Continue statement Return statement Raise statement On statement Resume statement Null statement Compound statement Programming model Function definition Class definition Method definition Finalize method Attribute definition Modules, libraries and dictionaries GLUEPATH Module initialization Global constants Usage errors Multiple threads of execution A complete example: Multi-threaded file scanner Post mortem debugger (PMD) Debugging GLUE programs Using the GLUE debugger Manipulating debugger lists Source view Command view Call stack view Modules view Functions view Methods view Global variables view Local variables view Inspector windows GLUE tools Glue Glued Classify ClassInfo class Unglued Elmer Elsie Glucose DrGlue Sample DrGlue documentation FileChgExt LastPos Point DocView The GE editor Starting GE Editing basics Files Views Marks Bookmarks Bounce bar menus Prompts The command shell File lists Scan lists Editing functions Editing GLUE source files Modifying the editor Predefined GLUE functions GLUE built-in functions AddrOf GluePath Module OnEnv OnError Resource Tracing Use UseRexx Variable XCall GLUELIB functions Abort Call CallStack ClassOf CmdLine CmdName Compile Concat Defined Elapsed Error Exec ExtLibPath FileClose FileDate FileDel FileDrive FileEA FileExt FileFind FileFlush FileIni FileLen FileName FileOpen FilePath FileRead FileRoot FileType FileWrite Input InstanceOf Interpret Lock MethodOf ObjectOf OS2Info Pointer Post Replace Result Rotate Say Send Sleep Start Stop Struct SuperOf SysEnv SysKillPID SysOS SysPID TagOf Thread UnLock VideoMode Wait GLUEREXX functions Abs Beep C2D C2X Center Copies D2C D2X Date DelStr DelWord Directory Insert Left Length Max Min Overlay Pos Random Reverse Right Sign Space Storage Strip Substr SubWord Time Translate Verify Word WordIndex WordLength Words XRange GLUEVIO functions VioCol VioCols VioCursor VioEvent VioGet VioPut VioRow VioRows VioScroll GLUESOCK functions SocketAccept SocketBind SocketBlock SocketClose SocketConnect SocketError SocketHostName SocketListen SocketLocalId SocketOpen SocketReceive SocketSend SocketServer User supplied GLUE functions GlueAbort Utility functions and classes written in GLUE ArrayCopy ArrayDelete ArrayInsert FileChgExt ForEachCommandOption ForEachCommandWord ForEachDir ForEachElement ForEachFile ForEachWord LastPos LoadUserSettings LowerCase Percentage QuotedString Repeat RestoreValueOf SaveUserSettings SaveValueOf ShowGlueHelpTopic Substitute Array Bag BeepQueue Dictionary Named NamedValue Profiler Queue SaveRestoreValueOf ServerQueue SharedArray SharedScalar Stack Tally TextFile Text window prompt function Pull Sorting routines written in GLUE QSort QSortAsc QSortB QSortDesc QSortF RSort TCP/IP socket class Socket Execution tracing Trace TraceOff TraceOn Tracer Writing GLUE functions in C GLUE calling conventions GLUE helper functions ggnum -
