DEV

McIDAS-X User's Guide
Version 2021.1

This keyword specifies the destination device of text output generated by a command. The format of the DEV keyword is shown below.

DEV=device filename file_option
DEV=device 'print_command'

device	1-, 2- or 3-letter string indicating destination for each of the three output types (standard, error, and debug); the first letter directs standard (non-error) output, the second letter directs error output, the third letter directs debug output; do not specify both F and T together, for example, DEV=FTT; the letters below are valid options (default=CCN)
	C	sends output to the text frame
	F	sends output to an LW file
	N	suppresses output
	P	sends output to the default printer
	T	sends output to a text file
filename	the name of the LW or text file for saving output; specify only when device includes F or T
file_option	A	appends the output to the specified file
	R	replaces the output in the specified file (default)
'print_command'	Unix print command; valid only when device includes a P; if 'print_command' is not specified, then the value of the MCPRINT environment variable is used; if 'print_command' is not specified and MCPRINT is not set, then the default lpr command settings are used

See the FRMSAVE command for information about printing image and graphics output.
