RPG Question

Doug,

The Retrieve Network Attributes (QWCRNETA) API will do this.  Here is
an "as-is" sample of using the API to access the system name.  The sample
does assume you have OS/400 option 13 (QSYSINC - Openness includes)
installed.

     I/COPY QSYSINC/QRPGSRC,QWCRNETA
     I/COPY QSYSINC/QRPGSRC,QUSEC
     I* Declare the receiver variable
     IRCV         DS                            256
     I                                    B   1   40NUMBER
     I                                    B   5   80OFF1
     I* Declare the size of receiver, number of network attributes to
     I* retrieve, and the attribute to retrieve (respectively)
     IMISC        DS
     I I            256                   B   1   40RCVSIZ
     I I            1                     B   5   80NBR
     I I            'SYSNAME'                 9  18 NETA
     C* Set error reporting to exception mode
     C                     Z-ADD0         QUSBNB
     C* Call Retrieve Network Attributes API
     C                     CALL 'QWCRNETA'
     C                     PARM           RCV
     C                     PARM           RCVSIZ
     C                     PARM           NBR
     C                     PARM           NETA
     C                     PARM           QUSBN
     C* If we got here, then no exception took place
     C           NUMBER    IFEQ 1
     C* So, adjust the offset from base 0 to RPGs base 1
     C           OFF1      ADD  1         OFF     30
     C* Get the header information for the network attribute
     C           16        SUBSTRCV:OFF   QWCBV
     C* Adjust OFF to address the returned value
     C                     ADD  16        OFF
     C* Check for system name being returned
     C           QWCBVB    IFEQ 'SYSNAME'
     C* Blank out any residual data from SYSNAM
     C                     MOVE *BLANKS   SYSNAM  8
     C* Get the returned value
     C           QWCBVF    SUBSTRCV:OFF   SYSNAM
     C* Display the system name
     C           SYSNAM    DSPLY
     C                     END
     C                     END
     C* And get out
     C                     MOVE '1'       *INLR
     C                     RETRN
