Just try it out ...

    WORKDIR="SOME WORK DIR"
    S=${WORKDIR}/SUBDIR
    echo ${S}

    Output: SOME WORK DIR/SUBDIR

... and you will see that this works.

Although on the other hand you can't do ...

   S=SOME WORK DIR/SUBDIR
   echo ${S}

   Output: -bash: WORK: command not found

... or ...

   S=${WORKDIR}/SUB DIR
   echo ${S}

   Output: -bash: DIR: command not found

... as then things end up breaking as they are seen as commands.

It's up to you whether you use them or not; while "..." helps you spare
out on characters in some cases, in other cases not having them
requires you to define an extra variable. Depends on what you prefer...
