LET 90 192 IP address of connection destination (H) = 192

LET 91 168 IP address of connection destination (MH) = 168

LET 92 72 IP address of connection destination (ML) = 72

LET 93 101 IP address of connection destination (L) = 101

LET 94 64514 Port number of connection destination = 64514

IPCN 31 90 Declare the IP address/port number storage area for the

connection destination of channel 31 = Local integer

variable between 90 and 94.

SCHA 10 Specify 10 (= LF) as the end character.

OPEN 31 990 Open channel 31.

TRAN 1 99 Store the return code in variable 1.

N 990 GOTO 15 OPEN failed  Proceed to error handling or retry

process after closing.
