Finding Memory Block Size

[Bolt]

Is there a way in ladder logic to determine the size of a memory block?  Say I want to know what the block size is on a string memory.  SS.Max or something like that.

DATAINFO instruction.  You can query the number of elements, the size in bytes of the block, the data type, et. al.

Thanks!  You guys thought of everything!

I try to utilize that in some of my FOR/NEXT code-blocks, whenever I know there's a good chance I will be tweaking the block size.  I don't want to have to remember to change CODE if I change the size of a data block from 100 elements to 200 elements.

Exactly what I'm trying to do, anticipating a future memory block size adjustment, and building a queue system that will "never" get full.
