MemSet will set a range of memory to a specific value. To allocate memory,
you should use MemPtrNew (x) or MemHandleNew (x), where x is the amount of
memory, in bytes, that you want. x should be of type unsigned long.

I don't thinkI allocated space for it at all! Should I use MemSet()?
Cheers,

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?
