Characters missing in output file?

Hi all,

In the below code I am not able to see the characters from 500 onwards in output file. What might be the reaon?

PARAMETERS:P_OUTPUT type rsfillst-dirname

DEFAULT TEXT-001 lower case.

data:vtext(900) type c.

start-of-selection.

vtext+0(5) = 'abcde'.

vtext+100(5) = '1bcde'.

vtext+200(5) = '2bcde'.

vtext+300(5) = '3bcde'.

vtext+400(5) = '4bcde'.

vtext+700(5) = '7bcde'.

vtext+895(5) = '9bcde'.

OPEN DATASET P_OUTPUT FOR OUTPUT in text mode encoding default.

TRANSFER vtext TO P_OUTPUT.

CLOSE DATASET P_OUTPUT.

IF SY-SUBRC = 0.

WRITE:/ 'ok'.

ELSE.

WRITE:/ 'FAIL'.

ENDIF.

-

I can see only characters till '4bcde' in output file.

Please help.

Thanks,
