    Not too obvious..
    And I assume you mean '\0' rather than "\0"...
     REPEAT WHILE BYTE[noparse][[/noparse]the_string]


    or
     REPEAT WHILE BYTE[noparse][[/noparse]the_string]<> 0


    or
     REPEAT UNTL BYTE[noparse][[/noparse]the_string] == 0


    "the_string" is a pointer; don't forget to increment it (++)

    Hi deSilva
    Thanks

    It is corect ????

    repeat i from i to i < yme|i++
    ' for (i=0|i < yme|i++) ' // 10 bytes per char 15
    '{ //
    Mask := $80
    j := x
    repeat j from j to j < (x + xme)|j++
    'for (j=x|j < (x + xme)|j++)
    '{ //
    z := y + i
    ' //
    if (@Data & Mask)
    '{ //
    LCD_PixelPut (j,z,fcolor)
    '} ' //
    if not (@Data & Mask) ' else
    '{ //
    LCD_PixelPut (j,z,bcolor)
    '} ' //
    Mask>>=1
    '} //
    Data++
    x+=xme
    the_string++
    '}

    REPEAT WHILE BYTE[noparse][[/noparse]@the_string] == 0 ' //· while(@the_string !="\0") keep spitting chars until end
    ' //
    SendLcd(LCDCommand,nNOP) '· //· Recomended to send now and then



    Prppeller Tools compile it ! but I still not run it.

    Sorry, no - most of it is simply poppycock.
    repeat i from i to i < yme|i++ ' for (i=0|i < yme|i++) ' // 10 bytes per char 15


    C has no nice for loops; SPIN has - please look into the manual
    correct would be: REPEAT i FROM 0 TO yme-1

    j := x
repeat j from j to j < (x + xme)|j++ 'for (j=x|j < (x + xme)|j++)


    correct would be: REPEAT j FROM x TO x+yme-1

    if (@Data & Mask)


    What do you want to say with "@Data" ???
    if not (@Data & Mask) ' else


    Use ELSE by all means

    REPEAT WHILE BYTE[noparse][[/noparse]@the_string] == 0 ' //  while(@the_string !="\0") keep spitting chars until end


    This makes hardly any sense! Where is "the_string" incremented? You must use a pointer, to be de-referenced by BYTE[noparse][[/noparse]..]

    Hi deSilva

    Sorry I have not manual till Propeller spin Programing.

    I only learn mig from code on forum and I know att it looks bad.

    Hi deSilva

    What do you want to say with "@Data" ???

    It is Variable to hold temporary address to pixel table on every character

    Where is "the_string" incremented?

    one rad before repeat

    Maybe, but "@" makes no sense at all..

    This also makes no sense - it has do be done inside the repeat-loop.

    Please post your code again; when you sorround it by "[noparse][[/noparse] code ]" and "[noparse][[/noparse] /code]" it will also look nice.

    All your REPEAT loops are terribly wrong! So take your time to think about it.

    Hi deSilva

    I think about it but for it I most understand Spin programing.
    And it take up little time
