I really could do with a little help with this one.

This sub routine breaks up a line into words, it also detect delimiters as I need to know what delimiter it has found.

SUB ColourLineZ(INT id,INT LineNoIn,ISTRING LineToWords[255],INT Offset)
    LineLen = LEN(LineToWords)
    WordIn = ""

    SENDMESSAGE(id,EM_SETSEL,1+Offset,LineLen + Offset)
    cf.dwMask = CFM_COLOR
    cf.crTextColor = RGB(0,0,0)
    cf.cbSize = SIZEOF(cf)
    SENDMESSAGE(id,EM_SETCHARFORMAT,SCF_SELECTION,&cf)

    FOR b1 = 1 TO LineLen    '<----------- this

        ThisPos = b1 + Offset
        Letter = LineToWords[b1-1]  '<------ and this
        Del = INSTR(CheckLetter2,Letter)

        SELECT Del

                CASE 0 'Add character to our word
                    'aw = instr(KeyWordLetters,ucase$(Letter)) 'Only alphabet characters a to z plus $ _ and @ symbols
                    WordIn = WordIn + Letter

                CASE 1 'Quotes
                    WordIn = ""
                    StartPos = b1 + (Offset-1)
                    DO
                        b1 ++
                        Letter = LineToWords[b1-1]
                    UNTIL Letter = CHR$(34) OR b1 = LineLen
                    EndPos = b1 + Offset
                    'EndPos = instr(LineToWords,chr$(34),StartPos+1) + Offset

                    SENDMESSAGE(id,EM_SETSEL,StartPos,EndPos)
                    cf.dwMask = CFM_COLOR
                    cf.crTextColor = Purple
                    cf.cbSize = SIZEOF(cf)
                    SENDMESSAGE(id,EM_SETCHARFORMAT,SCF_SELECTION,&cf)

                    IF b1 = LineLen THEN RETURN

                CASE 2 ' comment symbol
                    WordIn = ""
                    StartPos = b1 + (Offset-1)
                    SENDMESSAGE(id,EM_SETSEL,StartPos,LineLen + Offset)
                    cf.dwMask = CFM_COLOR
                    cf.crTextColor = Green
                    cf.cbSize = SIZEOF(cf)
                    SENDMESSAGE(id,EM_SETCHARFORMAT,SCF_SELECTION,&cf)
                    RETURN

              'case 7 'Local subroutine check
                        'if Subs[LineNoIn]  'Local subroutine
                          'StartPos = (ThisPos - len(WordIn))-1
                          'EndPos  = ThisPos-1
                          'SendMessage(id,EM_HIDESELECTION,1,0)
                          'SendMessage(id,EM_SETSEL,StartPos,EndPos)
                          'cf.dwMask = CFM_COLOR
                          'cf.crTextColor = Claret
                          'cf.cbSize = sizeof(cf)
                          'SendMessage(id,EM_SETCHARFORMAT,SCF_SELECTION,&cf)
                          'SendMessage(id,EM_HIDESELECTION,0,0)
                          'breakfor
                        'endif
                    'SendMessage(id,EM_SETSEL,EndPos,EndPos)
                    'goto DoDefault

                CASE 18 'Remove carriage return from last word on line
                    WordIn = MID$(WordIn,1,INSTR(WordIn,CHR$(13))-1)
                    IF LEN(WordIn)> 1
                        WordIn = ChangeWordEditorZ(id,WordIn,(ThisPos - LEN(WordIn))-1,(ThisPos)-1)
                    ENDIF
                    RETURN

                DEFAULT 'Other delimiter - so we have our word
                    LABEL DoDefault
                    IF LEN(WordIn)> 1 'Key words are at least 2 characrers long
                        StartPos = (ThisPos - LEN(WordIn))-1
                        EndPos  = ThisPos-1
                        WordIn = ChangeWordEditorZ(id,WordIn,StartPos,EndPos)
                    ENDIF
                    WordIn = ""

        ENDSELECT
    NEXT b1

RETURN
ENDSUB


Now I know INSTR can have an option start position for a string, so instead of using a FOR / NEXT loop to loop through each character in the string I was wondering how this sub routine could be changed.

I need to know the " character, the "'" character and the "(" ")" characters.

Anyone fancy a little challenge?

Would be appreciated!

Thanks,
Andy.

Perhaps the xinstr command from the Fletchie's control pak can help here ?

Thanks Hecktor, will have a look now I finally have a little time after a busy few days.

Thanks again,
Andy.

This can be a starting point. The code breaks up each part of a subroutine:

$INCLUDE "windowssdk.inc"

OPENCONSOLE
string indata = "SUB MyFunc(INT value, string text), INT"
string sep = "(),"

PRINT
PRINT indata

string stdata = indata ' indata copy
pointer pdata = &indata ' indata address
pointer token = strtok(indata, sep)

WHILE token
PRINT
PRINT "str: " + RTRIM$(LTRIM$(*<string>token))
PRINT "pos:" + STR$(token - pdata)
IF token - pdata THEN PRINT "sep: " + MID$(stdata, token - pdata, 1) ELSE PRINT "sep: no sep"
token = strtok(NULL, sep)
   ENDWHILE

DO:UNTIL INKEY$ <> ""
CLOSECONSOLE


Thanks Fasecero,

You are always a very big help!

Will play around with this to see if it helps me.

Thanks again,

Andy.
