A simple search at Google with the keys 'TINN' or 'Winedit' will provide further information. Yes. TINN will send the entire lines just like a clipboard paste into R console Thanks for your comments. I think that source() is the way as mentioned by Jim Holtman. Please give-me some time to clarify my problem with my concrete example.

Just as will pasting multiple lines into an interactive R session -- that is intentional. I don't know what you mean by 'TINN' and 'Winedit' (what exact program, how are you using them?) but suspect that they are working just like pasting lines into the R session, or R-for-Windows' own pager and script editor. > Is there a way to interrupt the code of being read from a text interface? stop() breaks execution of a block of code that source()d -- maybe that is what you are looking for? -- Brian D.
