For a procedure, the 1775-S4B scanner lists the extended address for the
message area location. This address starts with E5. The size is the number
of words that make up the procedure.
For a symbolic address, the 1775-S4B scanner lists the corresponding
logical address. This address could be displayed in extended address or
data table address format. The 1775-S4B scanner does not display the size
for symbolic addresses.
Example using the directory command:
If you enter:
S4B> DI [ENTER]
The 1775-S4B scanner returns:
Directory Ć System Symbols
NAME ADDRESS SIZE
MP_1 $E5.1.1.0.0 127
A1B $E0.0.0.7
REPORT $E5.1.1.1.0 12457
MP_2 $E5.1.1.2.0 765
COUNT $N1:23
In the example directory above, @MP_1, @A1B, and @REPORT are
global system symbols. The other symbols @MP_2 and @COUNT are
local system symbols. The size column shows the number of words used to
store each message. Thus, @MP_1, @REPORT, and @MP_2 are
procedures, and @A1B and @COUNT are symbolic addresses.
Definition: To define a symbolic address.
Abbreviation: CR
Format: CR/ @ $address>
Description: You can use the create command to generate a symbolic
address. The symbolic address is a system symbol which represents a
logical address. The 1775-S4B scanner stores the symbolic address and its
corresponding logical address in the system symbol table. You can use the
global modifier (/G) to create a symbolic address which the 1775-S4B
scanner will recognize in any context. Refer to chapter 8 for detailed
information on system symbols. The local modifier is the default scope
modifier.
