ZRDSUM

Concatenates two ZRD files into a third file. This command only makes sense to use if the two ZRD files were traced in the same system, as no attempt is made to modify object numbers or coordinates.

Syntax:

ZRDSUM infilename1, infilename2, outfilename

Discussion:

This keyword requires the name of two input ZRD files and the name of the output ZRD file. For information on the ZRD format, see "Ray database (ZRD) files". The file names may each be defined by either a literal string or a single string variable. The file names must include the full path name. Although any extensions may be specified, the extension ZRD is recommended for all three file names. The input and output file names must be distinct. Both input files must use the same ZRD format, and the output file will use this same ZRD format. See also ZRDAPPEND.

Example:

ZRDSUM "C:\TEMP\TEST1.ZRD", "C:\TEMP\TEST2.ZRD", "C:\TEMP\TEST_SUM.ZRD"
