Storing values from loop in idl

[taylrl3]

Hey!

I am using IDL and want to store the values found using a loop. The only problem is each time the loop goes round, it re-writes all the values in the array. How do I store the values for use once the loop has finished? Seems like a really simple thing to want to do, I am surprised I can't do it or havn't had to do it before. Anyways here is what I have got so far, I've had a go but it doesn't work:

for num=0, 32 do begin

DMID=(Basically I read the values into this array from 32 separate files)

result=where(DMID, count)

imin=-1
imax=0

for imin, imax do begin
imax=imax+count
DMIDs[imin:imax]=DMID
imin=imin+count
endfor

endfor

This doesn't work anyway and seems like a slightly mental way of going about it to me but its what a friend told me to do. Any help, most appreciated.

Thanks!The way you are trying to do it is not the most efficient way. You could use an array of pointers to store the values from each file. This way, once your loop is finished, you can access the values stored in the array of pointers directly. Here is an example of how you could do it:dimensions = 32pointer ptr[dimensions]for num=0, dimensions-1 do begin DMID=(Read the values from each file into this array) ptr[num] = pointer(DMID)endforOnce your loop is finished, you can access the values stored in the array of pointers using ptr[index], where index is the index of the array.
