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...
