Further information
1. The first argument of the routine is interpreted as a list of flags if it starts with a '-'.
2. If the flag "-d" is used, the following argument is interpreted as a directory name from where the command will be executed.
3. With the flag "-t", leading and terminating spaces are removed and all newline characters are replaced by spaces.
4. The command can be given either as a single string or as a list of strings. In this case the first one is the command itself and each following one an additional argument.
5. The status of the execution should be checked with getsysstat.
