Back in 1980, I ported a "tiny" Pascal compiler (found in Byte Magazine, written in BASIC) to the Apple II. In order to perform any file access from my Pascal programs (which had an Assembly language runtime environment) I had to prefix the CTRL-D with a CTRL-M. It seemed that whenever the last character typed before a DOS command prefix (CTRL-D) was not a carriage return, the command was ignored. -- Paul Sander (408) 734-9822 | Do YOU get nervous when a paul@Atherton.COM | sys{op,adm,prg,engr} says {decwrl,sun,hplabs!hpda}!athertn!paul | "oops..." ?
