// Scintilla source code edit control
// @file LexPB.cxx
// Lexer for PowerBasic by Roland Walter, roland@rowalt.de (for PowerBasic see www.powerbasic.com)
//
// Changes:
// 17.10.2003: Toggling of subs/functions now until next sub/function - this gives better results
// 29.10.2003: 1. Bug: Toggling didn't work for subs/functions added in editor
// 2. Own colors for PB constants and Inline Assembler SCE_B_CONSTANT and SCE_B_ASM
// 3. Several smaller syntax coloring improvements and speed optimizations
// 12.07.2004: 1. Toggling for macros added
// 2. Further folding speed optimitations (for people dealing with very large listings)
//
// Necessary changes for the PB lexer in Scintilla project:
// - In SciLexer.h and Scintilla.iface:
//
// #define SCLEX_POWERBASIC 51 //ID for PowerBasic lexer
// (...)
// #define SCE_B_DEFAULT 0 //in both VB and PB lexer
// #define SCE_B_COMMENT 1 //in both VB and PB lexer
// #define SCE_B_NUMBER 2 //in both VB and PB lexer
// #define SCE_B_KEYWORD 3 //in both VB and PB lexer
// #define SCE_B_STRING 4 //in both VB and PB lexer
// #define SCE_B_PREPROCESSOR 5 //VB lexer only, not in PB lexer
// #define SCE_B_OPERATOR 6 //in both VB and PB lexer
// #define SCE_B_IDENTIFIER 7 //in both VB and PB lexer
// #define SCE_B_DATE 8 //VB lexer only, not in PB lexer
// #define SCE_B_CONSTANT 13 //PB lexer only, not in VB lexer
// #define SCE_B_ASM 14 //PB lexer only, not in VB lexer
// - Statement added to KeyWords.cxx: 'LINK_LEXER(lmPB);'
// - Statement added to scintilla_vc6.mak: '$(DIR_O)\LexPB.obj: ...\src\LexPB.cxx $(LEX_HEADERS)'

//The folding routine for PowerBasic toggles SUBs and FUNCTIONs only. This was exactly what I wanted,

//GFA Basic which is dead now. After testing the feature of toggling FOR-NEXT loops, WHILE-WEND loops
//and so on too I found this is more disturbing then helping (for me). So if You think in another way
//you can (or must) write Your own toggling routine ;-)
