A scm file is a binary file with certain structure. The common information about what this file is for can be found here. The scm file structure looks like the following: ====(02 00 01)h + 32 bit int Jump to second segment byte Padding

(Global vars)              Space for variable saving

(02 00 01)h + 32 bit int Jump to third segment byte Segment id

32 bit int                 Number of models
 (model names)              24 byte model names * number of models(model 0 not used)

(02 00 01)h + 32 bit int Jump to fourth segment byte Segment id

32 bit int                 MAIN size
 32 bit int                 Largest mission size
 32 bit int                 Number of missions
 32 bit int                 Highest number of locals used in mission/exernal
 (mission addresses)        32 bit addresses * number of missions

(02 00 01)h + 32 bit int Jump to fifth segment byte Segment id

32 bit int                 Largest external size
 32 bit int                 Number of externals
 (external data):           28 byte external data * number of externals
   20 bytes                 Name of external
   32 bit int               Offset of external
   32 bit int               Size of external

(02 00 01)h + 32 bit int Jump to sixth segment byte Segment id

32 bit int                 (Unused)

(02 00 01)h + 32 bit int Jump to seventh segment byte Segment id

32 bit int                 Size of global var space
 32 bit int                 (Unused)

(MAIN code) MAIN section, equal to size defined earlier (mission code) The mission data, missions stored at offsets defined earlier====
