Hi,

I've writen a program in qbasic to perform a specific task. Now, the problem is that the variable v (v1,v2,v3)must be not a single double ( 4 bytes ) but an IEEE double ( 8 bytes ) - the following programs force me to have the values in this format.
The code I've written is as follows:

CLS
DIM v AS DOUBLE
n = 0
ON ERROR GOTO 1000
OPEN "c:\jpl408\jpleph.408" FOR INPUT AS #1
OPEN "c:\jpl408\408.txt" FOR BINARY AS #2
r=SEEK (2)
DO UNTIL EOF(1)
LINE INPUT #1, a$
a$ = LTRIM$(a$)
v1 = 0: v2 = 0: v3 = 0
i = INSTR(1, a$, " ")
v1 = VAL(MID$(a$, 1, i - 1))
a$ = LTRIM$(MID$(a$, i + 1)): i = INSTR(1, a$, " ")
v2 = VAL(MID$(a$, 1, i - 1))
a$ = LTRIM$(MID$(a$, i + 1))
v3 = VAL(MID$(a$, 1))
i = INSTR(1, a$, "D")
IF i >= 1 THEN PUT #2, , v1
IF i >= 1 THEN PUT #2, , v2
IF i >= 1 THEN PUT #2, , v3: n = n + 1: LOCATE 1, 1: PRINT n
LOOP
CLOSE
END
1000 i = 0: RESUME NEXT



I think that this must be programed in Visual Basic. Another problem, is that the results overwriten the existing data in 408.txt

Can someone help me making the necessary changes? As always this is very urgent.

Regards,

Kepler

Wow, this is kind of out of the scope of web development. You might have more luck with this one on a programming forum Smile

Also, moved to Chit Chat.
