This variable enables the use of IPv6 addressing.
By default, this variable is set to 0 and IPv4 addressing is used instead. Set the variable to 1 to enable IPv6 addressing.
If your program is not using a configuration file, you can set AGS_USE_IPV6 within the runtime environment; if your program does use a configuration file, you can set the variable in either. In some cases, such as acurcl -start , the variable must be set in the configuration file, because a child process is spawned that does not inherit the environment of the parent.
For best results, unless otherwise necessary, use the same AGS_USE_IPV6 setting for all ACUCOBOL-GT programs or client/server environments.
It may be possible to mix IPv4 and IPv6 addressing between client and server, but controlling that behavior is beyond the scope of ACUCOBOL-GT. Refer to your system documentation for more information on the effects of mixing addressing versions.
In ACUCOBOL-GT, you specify an IPv6 address in the same way as you would an IPv4 address:
SERVER_IP 1111:2222:3333:4444:5555:6666:7777:8888
However, if the address contains additional notation, square brackets must be placed around the address; for example:
CODE_PREFIX *[1111:2222:3333:4444:5555:6666:7777:8888]:/usr/acu/code
