winIDEA can only modify values of expressions that evaluate to a target system address (also called Lvalues). You can not modify constant expressions or Rvalues. Here are some expressions whose value can be modified:

c                        variable 'c'
:0x1000                memory at address 1000h

and following can't:

1                        constant
c+1                        Rvalue

To modify value of an expression you can:

click in the value column of the expression you wish to modify

enter the new value. This can be any valid watch expression.

Note: If the expression does not change, the CPU might have problems with write access to that location.
