MexScript

BMS stands for Binary MultiEx Scripts. It is the format used by MultiEx Commander to take apart an impressive array of GRAFs. The file format consists of a text file which a series of instructions to be run through an interpreter. The interpreter uses the instructions to traverse through a GRAF file and search for key data such as names, offsets, and sizes of various constituent files.

Basics

Each line of a BMS script contains a single statement. The statement can be broken down into a series of tokens.

Questions: Are all statements constrained to one line? or can they span multiple lines? If the former, then the semi-colon at the end of each line seems superfluous. Or can there be comments after the semi-colon?

Statements

The first token on a statement line indicates what operation that line is to perform. These are the known statement types:

• Do
• FindLoc
• For
• Get
• GetDString
• GoTo
• IDString
• ImpType
• Log
• Math
• Next
• SavePos
• Set
• While

Comments

Does BMS make provision for comments?

Case Sensitivity

Is BMS case sensitive? Does it have to be written as IDString, or will idstring or iDstrINg both work?
