[RS]: The most traditional way of programming, a sequence of instructions to be executed, 
 do this
 do that
 do another_thing
possibly with jumps (see [GOTO in Tcl]) to other places. Contrasts with [functional programming]. I'm not sure about [OO], where objects are just told what to do...

[SS]: Also in [imperative programming] the program is expressed in terms of program state (usually hold into variables),
that is modified by statements executed sequentially, with conditional jumps (or more complex form of imperative
control structures like [for], [while]). The jump condition is usually about the state of the program.
