The globa l symbols di spla y ha s two pa rts. Th e first part s list s al l the

modules that were linked to produc e this ob je ct fil e. T he se m odu le

name s are used by you when you want to refer to a loca l symbo l, and

are case- sensi ti ve . The secon d par t of the displ ay list s all glo bal

Cmd_Input. The strings cmd_input or CMD_INPUT are not valid

System, Symbols, Local, Display

Enter th e name of th e modul e yo u want to spe ci fy (f rom the fir st pa rt of

Aft er you displa y local sym bol s with the “ System Symbols Local

sour ce f ile or loca l symbo l displa y. When you disp lay local sym bol s

for a giv en m odule , that mo dul e be comes the defaul t lo ca l sym bol

module.

If yo u hav e not disp la yed loc al symb ols, you c an st ill e nte r a loca l

Re me mber tha t th e only va li d mo dule name s are tho se li ste d in the first

part of the glob al symbols di spl ay, and are case-se nsi tive for

comp atibili ty with othe r systems (such as HP-UX).

When you incl ude the name of an source fil e with a local sym bo l, that

module beco me s the default loca l sym bo l modul e, as wi th t he “System

Loca l symbo ls m ust be from assem bly mo d ules tha t form the absolute

One thi ng to note : It is possi ble for a sym bol to be loc al in one mo dul e

and glo bal in anot her , which ma y result in some confu sion . For

exam pl e, suppo se sym bol “XYZ ” is a global in modu le A and a loca l

you loa d the abso lute file (and the cor resp ondi ng symbol data base ),

en tering “XYZ” in an expre ssion refers t o the sym bol f rom mo dul e A.

Then , if you di spl ay local sym bo ls fro m modu le B, ente ring “XYZ” in

an expr essi on re fers to th e sym bol from modul e B, not the glo bal

symbol. Now, if you again want to en ter “XYZ ” to ref er to the glo bal

sym bol from module A, you must d isplay the loc al symbols from

module A (since the glo bal sym bol is al so loc al to that module).

Loading loc al symb ols fr om a thi rd module, if it was li nke d wit h

modul es A an d B and did not co ntain an“ XYZ” local sym bol , would

al so ca u se “ XY Z ” to refe r to the g lob al sy mb ol from m od ule A.

Transfer Symbols to

the Emulator You can use the emulat or’s sym bo l-h and li ng capa bil ity to improve
