Syntax:var1 = readline(prompt = Enter any number : );or,var1 = readline(Enter any number : ); Taking multiple inputs in R language is same as taking single input, just need to define multiple readline() for inputs. If your OS runs in 8086 Real Mode, you can ask the BIOS for these, otherwise you need to do direct port I/O. You have to pass two arguments: $a0 = address of input buffer $a1 = maximum number of characters to read So you should do something like: la $a0, name li $a1, 20 Nevertheless, this shouldn't cause a crash since $a0 should still hold the address of firstPromptString that you set up for the printing, earlier, and that is valid writable memory.
