Sure? If rusty memory serves me right,
IC is "insert character" and ICM "insert character under mask",
the latter could be used to perform byte swaps and such.
For testing single bytes CLI is the instruction of choice.
Main difference of S/3x0 to PDP,VAX,68K is the lack of
auto-increment/decrement.
