Re: What is the function of WRITE_LN.0 & WRITE_LN.1 in REXX?
The empty string is supported as a stream name by the standard input/output functions CHARIN, CHAROUT, CHARS, LINEIN, LINEOUT, LINES and STREAM. Except in the cases of CHAROUT and LINEOUT, where it means "stdout", it is read just like the expression "stdin."
