Ram storage of long intergers to be modified by Modbus

[cam_male2003]

How is a long stored in ram? I just want to verify that this is right. If the Value is 50.
unsigned long maxdiff;
#byte maxdiff= 74

It stores it at location 74 is 50
and location 75 as 0

I want to modify the values in ram, is there an easy way to do this. Since modbus writes MSD to LSD, not LSD to MSD?

If I have a floating Number how do I handle that?

Lost in the fog... lol

This is an example from a post I made. It does have to swap the byte order as it copies the register locations into the packet.

I modified the sample code in the FAQ that stores a float in eeprom so that it stores and reads a long int (2 bytes) in eeprom. I suppose you can re-use the for-loops for your app.
