In the first place, you apparently missed the implication
that the program name handed to USER must be non-quoted.

Secondly "-a" < 2 is supposed to be an argument to the
command you're trying to execute, and not a query to it.
That's why I suggested you'd probably need a shell script.
Here's something to start with:

Write this shell script, and make it executable and
readable by all:

  #!/bin/sh
  # Shell Script named "flog"
  # This will loop and read the value for "argument"
  # every time anything is piped into it:
  while read argument
  do /usr/vsifax/bin/flog -a $argument
  done

I think this processing will give you a start on your
output processing table:

         If: NOT Start
       Then: gosub Start ; declare answer
       Then: getname = 2
       Then: answer  = getname
       Then: ' other stuff you want to do with "answer"
       Then; end
  Start  If: ' The USER command must be alone on a line by itself:
       Then: USER getname = /path/to/shell/script/named/flog
       Then: return ' above should be unquoted full absolute pathname
