I believe ${LOGNAME} ${PWD} are special ,,metacharacters'' that are interpreted by shell. bash, ksh are modern shells with a lot of capabilities, sh and csh are more simple shells that don't have all that fancy stuff.

shell is sort of programming language, in .vbs (forgive me this example here) a variable is simply wirrten like var, in perl/shell you need to write $var, what you spotted is simply one of differences between csh, sh, ksh, bash.
