select echo channel

command: ECHO_CH [<filename>]

Selects the text output channel. Any non-blank parameter opens an ASCII file name "<filename>.STX". If <filename> is omitted, the text channel is reset to the default channel (seismhandler text window). Any file previously opened is closed.

If the text channel is switched to an existing file, the following output is appended to the file, unless the /NEW qualifier is entered.

parameters

• <filename> parameter type: filename (no extension)
  Name of file to be opened as text channel. Any file previously opened is closed. If this parameter is omitted, the text channel is reset to the seismic handler text window.

qualifiers

• /new
  A new output file is created (output is not appended to an already existing file; creates a new version of a file on a VAX).

• /ovwr
  Overwrites an existing file (output is not appended).

example

echo_ch LOGFILE

appends all following ECHO-output to file LOGFILE.STX

echo_ch/ovwr LOGFILE

creates new output file LOGILE.STX; a possibly existing file of this name is deleted

echo_ch

closes a previously opened ECHO-file and switches output back to screen
