From the macro file:

22=L:KLID=SET //(Parameter for momentary button set in the FSUIPC window. for IAS it is 1701005
23=L:O03_001_BUT=Toggle  (Antiskid)
24=L:O15_001_BUT=Toggle  (Cont ignition)
25=L:U06_021_BUT=Toggle   (Pack1 Isolation)

From the L1011 ini file (in profiles) it will look  something like this after assigning in FSUIPC.

24=P0,10,CM9:23,0      -{Macro L1011: L:O03_001_BUT tgl}-
25=P0,11,CM9:24,0      -{Macro L1011: L:O15_001_BUT tgl}-
26=P0,5,CM9:25,0      -{Macro L1011: L:U06_021_BUT tgl}-


Hope this will help.
