conversion S5 to S7 (LIR and TIR)

hello
as i am beginer in conversion S5 TO s7 if find many problem this is one of them:

this is my interprétation in parts of FB1 with S5 code:

B MW 254 // the number of db opned is in MW254
:A DB 0
:SPA =M002
M001 :U M 195.5
:SPB =M002
:L MD 250
:L KH EC00
:TIR 2
:LIR 6 // the ofset in the db opned is in MD250
:TIR 3
:LIR 8
M002 :L KB 1
:T DR 0 // so DR( 0+ofset)
:L DW 3 //so Dw( 3+ofset)
:T MW 217


so if there is somone how tell me if i was wrong ?
and who can convert this part in S7 code?



for more details i attached all the S5 programm.

thanks for every body.
