OutStd()

Writes values to the standard output device.

Syntax

OutStd( <expression,...> ) --> NIL

Arguments

<expression,...>

This is a comma separated list of expressions whose values are output.

Return

The return value is always NIL.

Description

OutStd() evaluates <expression,...> and writes the resulting values to the standard output device. This allows for collecting output in a file when program output is redirected on the command line to the error device (c:\xhb\program.exe > logfile.txt).

Note:  if an xHarbour console application does not require sophisticated screen output, the commands ? and ?? can be replaced with OutStd() by including the file SIMPLEIO.CH.
