Re: Moving data into dynamic storage

[MWalter@xxxxxxxxxxxxxxx]

Let me take a shot

      * define the based parameter. 32767 is the max although because
      *  it is based, no memory is allocated.
     Dentry            S          32767    based(pEntry)
      * stuffToAdd could be anything up to 32767
     DstuffToAdd       S            100
      * size is the memory requirement of stuffToAdd
     DSize             S             10i 0
      * determine how much memory to allocate
     C                   eval      size = %size(stuffToAdd)
      * allocate it
     c                   alloc     size          pEntry
      * move your data
     c                   eval      Entry = stuffToAdd

OK, Gurus let me know what I did wrong.

Thanks,

Mark

Hello,

I've ALLOC'd some variable amount of storage, and now I want to move some
data into it.  I currently use the following idiom to base a character
variable onto a pointer:

D pentry          s               *
D entry           s            100    based(pentry)

Now, I can MOVEL some data into entry (up to 100 bytes), and it goes where
the pointer is pointing to quite nicely.

My problem is that since the amount of storage is variable, I don't want to
have to declare a fixed length for the 'entry' variable.

How can I copy data into the contents of pentry while avoiding a fixed
length restriction?

Regards,
Rich
