You can simulate this in your terminal session...

DJAS01::DDACHTERA$ sh sym x*
  X = "ASTERISK"
DJAS01::DDACHTERA$ x10:= slash-asterisk
DJAS01::DDACHTERA$ sh sym x*
  X = "ASTERISK"
  X10 = "SLASH-ASTERISK"
DJAS01::DDACHTERA$ @tt:
_DJAS01::DDACHTERA$ sh sym/all
  P1 = ""
  P2 = ""
  P3 = ""
  P4 = ""
  P5 = ""
  P6 = ""
  P7 = ""
  P8 = ""
_DJAS01::DDACHTERA$ sh sym x*
%DCL-W-UNDSYM, undefined symbol - check validity and spelling
_DJAS01::DDACHTERA$ sh sym x
  X = "ASTERISK"
_DJAS01::DDACHTERA$ sh sym x10
  X10 = "SLASH-ASTERISK"
_DJAS01::DDACHTERA$  Exit 
DJAS01::DDACHTERA$

$ SHOW SYMBOL/ACCESSIBLE	! Display "local" symbols belonging to
