SUMMARY
An FMH-5 Attach is used to carry a request for conversation to be established between two transaction programs. The following is an example Attach message in a PVI (Peer Verb Interface) trace. This is the first SNA message that flows to the remote system for conversation startup:   PVI    -- 12:05:05.65 PVI   751F0001->0302E453 LU 6.2 PVI                      MSGID:SWAT   MSGTYP:PRFLS  Sense1:0004 PVI                      Sense2:0000 PVI PVI    Header  at address 8297B0F8, 1 elements PVI   0B050004 00000800 E1000000 0100C500     <..............E.> PVI PVI    Element at address 829935BC, start 13, end 237 PVI   430502FF 1803D000 400430F0 F0F50F04      PVI   02C1D4C9 09017B30 09E53983 81E71A11     <.AMI..{0.V9caX..> PVI   C2C9D6D5 C5E3C6D9 4BE2D5C1 C4E5F0F2      PVI   F124280E 0D1E0500 01000800 00000000     <1$(.............>   PVI    0002FF00 9E12F500 9A12E200 9612A020     <......5...S.o.. >   PVI    00051001 00000023 D7C3F2F3 F9F9E2F1     <.......#PC2399S1>   PVI    4040F3F1 F7F9F0F0 F0F24040 40404080     <@@31790002@@@@@.>   PVI    00000000 00000000 00000026 C4C6C1C2     <...........&DFAB>   PVI    40F6F9F7 40F2F9F7 40404040 40404040     <@697@297@@@@@@@@>   PVI    40404040 40404040 4040C140 00000000     <@@@@@@@@@@A@....>   PVI    00000000 00000000 00000000 00000000     <................>   PVI    00000000 00000000 00000000 00000000     <................>   PVI    00000000 00000000 00000000 00000000     <................>   PVI    00000000 00000000 00000000 00000000     <................>         PVI    00                                      <.               > The following is the above FMH-5 Attach broken out using the IBM SNA Format Guide:   43 - Length
