This is  more of a shell question than an OS question.

bash and DCL are different.

$ bash
bash-4.4$ QUOTE='"'
bash-4.4$ ./test "Hello World" ${QUOTE}Hello World${QUOTE}
Hello World
"Hello
World"
bash-4.4$ exit
exit

$ quote = """"""
$ mcr sys$disk:[]test "Hello World" "''quote'"Hello World"''quote'"
Hello World
"Hello
World"
