如何擷取如 NETSTAT 指令的網路狀態？(使用 API QTOCLSTNETCNN)
由於指令 NETSTAT 無法直接在程式中直接產生報表，需由人工由指令 NETSTAT 進入
Work with TCP/IP Network Status 畫面選 '3' 進入 Work with TCP/IP Connection Status
按功能鍵 F6 才能輸出報表。
但可使用 API QTOCLSTNETCNN，自動產生報表或做某些查詢。
File : QRPGLESRC
Member: NETSTATR
Type : RPGLE
Usage : CRTRPGMOD MODULE(NETSTATR) SRCFILE(xxx/QRPGLESRC) SRCMBR(NETSTATR)
CRTPGM PGM(NETSTATR) BNDSRVPGM(QTOCNETSTS)
CALL NETSTATR 後，WRKJOB 選 4 再選 5 查看 QSYSPRT 報表內容。
