OPTION USAGE LZX options may be specified anywhere on the command line, and begin with the dash (-) character. The option letter(s) and any optional parameter(s) should follow the dash character. Example Comment LZX a testfile.lzx dh0:test No options LZX -x x testfile.lzx -x option LZX x -x testfile.lzx -x option (same effect as above) LZX x testfile.lzx -x -x option (same effect as above) LZX -bi32 x testfile.lzx -bi option with parameter "32" LZX -x -a0 a testfile.lzx dh0:test -x and -a0 options LZX a -x testfile.lzx dh0:test -a0 -x and -a0 options (same as above) Since LZX allows options to appear anywhere on the command line, the following command could be considered ambiguous: "LZX a testfile.lzx -testfile2". In this case one is actually trying to add a file which has a name starting with the dash (-) character. LZX would take "-testfile2" to be the "-t" option with "estfile2" as a parameter. To solve this problem, the double dash (--) option exists; LZX will not parse any options on the command line after a double dash. To correctly perform the above command, one would use: "LZX -- a testfile.lzx -testfile2". The double dash, like any other option, can be placed anywhere on the command line, but must appear before the "-testfile2" parameter.
