If you are on the command line, then:
'What is your name? print.
('Hello, ', (stdin readLine) printLine.
should do it. print and printLine currently by default print to stdout.
The only tricky bit is that the prompt (repl) is reading and writing at the same time as you are, so it could steal some of your input or write over some of your output. It is best to suspend the prompt's process while you are using stdin.
If you file in the attached by doing 'path/to/prompt.self' runScript , you should then be able to do
prompt suspendWhile: [ stdin readLine printLine ]
which should do what you want. Let us know how you go...
