I'm a bit confused by your intention here:
voltage = SysRandom(0);
StrIToA(voltagetxt, voltage);
DmWrite(recordp, i*sizeof(voltage), &voltagetxt, sizeof(voltage)/8);
You're writing sizeof(voltage)/8 bytes, which is zero unless voltage is a double long.
And you've just converted voltage to voltagetxt which is a C string, so I assume
you're trying to write the string representation of voltage to the record, not the
integer representation. If so, use StrLen(voltagetxt) not sizeof(voltage) for the last
parameter, and recalculate the DmWrite index parameter appropriately. Or, if you're
trying to write the integer value to the record, pass &voltage to DmWrite, not
&voltagetxt. On a related note, did you allocate space for voltagetxt on the stack or
in the heap?
