I am still not sure why you say "file system clients".

Let me create a super simple example:

$ typ hoff.com
$ v = f$integer(f$logical("v"))
$ v = v + 1
$ write sys$output "Ran ''v' times"
$ define/job/nolog v 'v'
$ exit
$ @hoff
Ran 1 times
$ @hoff
Ran 2 times
$ spawn
%DCL-S-SPAWNED, process ARNE_11162 spawned
%DCL-S-ATTACHED, terminal now attached to process ARNE_11162
$ @hoff
Ran 3 times
$ eoj
   Process ARNE_11162 logged out at  8-OCT-2021 12:52:15.61
%DCL-S-RETURNED, control returned to process ARNE
$ @hoff
Ran 4 times

Is hoff.com a file system client?
