HELP POPDEVIN Revised by Fran Evelyn, July 85 popdevin -> device POPDEVIN is an active variable which holds the device for the standard input channel (read from by *CHARIN). Assigning to it, <device> -> popdevin enables a new device to be assigned to the standard channel, and can be used along with the updating POPDEVIN and POPDEVERR to redirect standard I/O after SYSFORKing a child process, and before SYSEXECUTEing a new image. See also REF *SYSIO - for more on Input/Output procedures HELP *CHARIN - reads in characters from the user's terminal HELP *POPDEVOUT - the device for the standard output channel HELP *POPDEVERR - the device for the standard error channel HELP *POPDEVRAW - the device for 'raw' input/output from the terminal HELP *SYSFORK - forks the current POPLOG process HELP *SYSEXECUTE - runs a file in place of current POPLOG image --- C.all/help/popdevin ------------------------------------------------ --- Copyright University of Sussex 1987.
