i found out its not a conventional string :O

its a string of 4 bit ints each representing anumber from 0 - 9
and its dynamicly allocated

i can find the individual digits each time. ( find the first - then each other is 4 bytes after ) with tsearch.

but when i exit tsearch it stops the app and the dma changes when i start it so i can use olly to see what going on

select addresses in dump window, right-click, select breakpoint > memory on access (or memory on write, as need be)

run prog, it will stop when (if) your data is accessed/changed
