Nobody is answering the question asked:

(paraphrase) "I don't understand the part after sys$output."

write sys$output f$getsyi("<sysgen parameter>")
<value>

WRITE needs little explanation.

SYS$OUTPUT, SYS$INPUT, SYS$COMMAND, SYS$ERROR are process-specific pre-defined IO channels for use by READ and WRITE; each correspond to different entities, mostly self-explanatory.

F$GETSYI is what is known as a lexical function.  Many exist, and are -very- helpful for manipulating the DCL/Console environment.  A non-obvious feature is that in addition to the list of specific qualities defined for it's use, F$GETSYI can also return the current value of any SYSGEN parameter.   

You can also do similar via MCR SYSGEN SHOW <param>, but the f$GETSYI approach allows the returned value to be placed into a symbol [variable] for programmatic use.
