error when reading datas from a file

Hi everybody,

I'm actually trying to make a pixel generator from a text file and i have an error in modelsim : (vsim-3543) TEXTIO procedure READ(INTEGER) : Parameter L designates an empty string.

my file seems like that :

3 1024 760

41 107 214 235 44 169 3 33 187 239

58 61 57 42 142 77 89 114 221 104

41 107 214 235 44 169 3 33 187 239

58 61 57 42 142 77 89 114 221 104

and my code is here:

FILE myfile : TEXT OPEN READ_MODE IS "fluxvid.txt";

BEGIN

PROCESS

VARIABLE fNumber : INTEGER range 1 to 3;

VARIABLE pnumber : INTEGER range 0 to 1024;

VARIABLE lnumber : INTEGER range 0 to 768;

variable buf : integer range 0 to 255;

variable buf_temp : unsigned(11 downto 0);

VARIABLE l: LINE;

BEGIN

READLINE(myfile,l); -- ... read a line ...

READ(l, fNumber); -- ... read the 1st element ...

READ(l, ipxl); -- ... and then the 2nd element

READ(l, jpxl); -- ... and then the 3nd element

IF (start_gen = '1') THEN

-- frame loop

FOR k IN 1 TO fNumber LOOP

fVal <= '1';

data_com <= (others => '0');

WAIT FOR 100 ns;

-- line loop

FOR i IN 1 TO lnumber LOOP

lVal <= '1';

-- pixel loop

FOR j IN 1 TO pnumber LOOP

READ(l, buf);

buf_temp := TO_UNSIGNED(buf, 12);

data_com <= STD_LOGIC_VECTOR(buf_temp);

WAIT FOR 10 ns;

END LOOP;

lVal <= '0';

END LOOP;

fVal <= '0';

WAIT FOR 100 ns;

END LOOP;

END IF;

END PROCESS;

Moreover, the data in the variable fNumber 41 instead of 3. I don't know where is my fault, i search on the web and didn't find the mistake.

Thx you for your answers !
