EXAMINE

        [SIC\]EXAMINE [Name] [/GLOBAL] [/FUNCTION] [/HEADER]

    List variables or functions.

    If the /FUNCTION option is not present, EXAMINE without  argument  gives
    the  list  of known variables with their respective types. Each variable
    name is followed by its definition and the  keywords  "GBL"  for  GLOBAL
    (interpreter  level  0)  variables,  LCL(lev)  for  LOCAL  variables  at
    interpretor level "lev"  (viz.,  in  a  procedure),  WR  for  READ/WRITE
    variables, RD for READONLY variables.

    With argument, EXAMINE will usually type the content  of  the  specified
    variable (local variables have priority). But:
      - If the argument ends by the % character, it is assumed  to  indicate
        an image header, and all associated header variables are listed.
      - Partial wildcarding is permitted: if the argument begins or/and ends
        with the "*" character, all compatible variables names  are listed.
      - In any case, typing an ambiguous variable name will generate a  list
        of choices.
    With the /FUNCTION option, lists the definition of the specified or  all
    (no command argument) user-defined functions.

    With the /GLOBAL option, lists only the GLOBAL variables, as opposed  to
    LOCAL variables (i.e, in a loop or a macro)

    With the /HEADER option, lists only the variables having  an  associated
    header (i.e., the known images).
