min/max hold in a device ?

[nebelfuerst]

I want to make some module for measurement of some statistics.
Now I want to find the minimal and maximal BPM, which occured after reset.

Although this should be an easy job in C/C++, it doesn't seem so in the scope SDK.

I spotted the "if" and a "compare T" and compare W", and I have a BPM-value ready for display.
Who can I make a max-hold with that modules ?
