Reset UDT in an array?

I am about perfomance.
Somebody tried to compare (depends of size)?

There are quite a few ways available to the programmer to clear a UDT or other block of memory:

LSET, ZeroMemory(), POKE$, use of pointers, DIM...AT, etc.

However, the request was for a single native BASIC statement to do the job.

What about API ZeroMemory ?

RESET is likely to be made to work with scalar variables in a future version of the compiler, but not individual array subscripts.

However, I'll suggest this idea to R&D. Thanks!

Thanks Lance!

I figured that much out but i still think it would be nice to have this feature in PBDLL/PBCC.

LSET UDT(0) = STRING$(LEN(UDT(0)), 0)

Hello All...

I just tried the following line and found that it didn't work, Would anybody also like to see this added to the next release?

type USERDATA
  dataname as asciiz * 257
  datasize as long
end type

dim user(%MAXUSERS) as USERDATA

reset user(0) <- This does not seem to work...?

This would be a great feature to have because it would allow a programmer to clear a UDT array element with one line rather than having to clear all the members one at a time. According to the help file you can clear a UDT though!
