Is there something that the docs did not cover?

You can but CommandLine is deprecated and will probably dissapear soon. Instead, you should use Executable and Parameters.

See the FCL documentation, and the TProcess section in the wiki page on Executing External Programs to see them in use.

If for some reason you have to start from a full command line, you can find a couple helpful functions in LazFileUtils: SplitCmdLine() and SplitCmdLineParams()

HTH!
