== Introduction ==

The IS_VER packet contains information about the LFS and InSim versions, allowing you to prevent your program interacting with legacy versions of the game. To request a IS_VER packet to be sent, either set the ReqI to non-zero in the [[IS_ISI]] packet when initialising InSim, or by sending a [[IS_TINY]] packet with a SubT of TINY_VER.

<big><pre>struct IS_VER // VERsion
{
byte Size; // 20
byte Type; // ISP_VERSION
byte ReqI; // ReqI as received in the request packet
byte Zero;

char Version[8]; // LFS version, e.g. 0.3G
char Product[6]; // Product : DEMO or S1
word InSimVer; // InSim Version : increased when InSim packets change
};</pre></big>

== Packet Detail ==

=== Size ===

The size of the packet, always 20.

=== Type ===

The type of packet from the ISP_ enumeration, always ISP_VER.

=== ReqI ===

Contains the ReqI as received in the request for an IS_VER to be sent.

=== Version ===

The LFS version, E.G. 0.5Z.

=== Product ===

The LFS product, E.G. S2.

=== InSimVer ===

The current InSim version, which at the time of writing is version 4. If this value does not match the version of InSim you are expecting, your program may not work correctly.
