Re: Multi-field dynamic array

I want to be able to increase the size of the array on an as needed
basis. I'm pretty sure this can be done with pointers, but I can't
figure out how. Can anyone offer some suggestions?


o Base the array on a pointer
o Set the array dimension to the maximum possible
o Use %ALLOC or ALLOC to allocate the initial amount of storage (size of element * expected elements) 
o Count how many entries you use
o When you approach the current maximum number of entries use %REALLOC or REALLOC to increase the array size (current size + (size of element * extra elements) 
o Minimise the number of %REALLOC calls
Don't use RPG functions that cannot be restricted to the current maximum size of the array.
