Here is a script that should help:

PARM file
# Assumes "file" is MPE syntax.  Note: you can use the fsyntax()
# function to make sure the name is an MPE name -- try help fsyntax
# Qualify the filename (also upshifts)
setvar qual_file fqualify("!file")
# Convert qualified name to POSIX syntax
setvar px_name dirname(qual_file)+"/"+basename(qual_file)
# move it using shell's mv command (you need to create the new name)
setvar new_name ?????
xeq mv.hpbin.sys "!px_name !new_name"
# Note the RENAME command can move a file across account boundaries,
# but you may have specific reasons to use 'mv'.

HTH,

p.s.  I did NOT test the above script, but I will help make it work
      if it does not as written.
