The path name of the directory to use as the initial working directory during execution of the job step. If none is specified, the initial directory is the current working directory at the time you submitted the job. File names mentioned in the command file which do not begin with a / are relative to the initial directory. The initial directory must exist on the submitting machine as well as on the machine where the job runs.
The syntax is:
initialdir = pathname
For example:
initialdir = /var/home/mike/ll_work
