Mathematica不能识别一个计算矿物化学式的软件？
 

各位好！我下载了一个关于矿物化学成分软件是基于Mathematica软件的，之前我有一点学习VB语言的基础，在用软件的过程中，可能是一个调用“B88”总是显示红色，不知是不是这个Mathematica软件不识别我下载的这个矿物化学成分计算软件：

(* This notebook contains examples for the PET-functions
-CalcFormula- calculate mineral formulae (and mole fractions)
-TransformDatFile- transform microprobe data-files (JEOL_JX \
8600) to PET-readable format
-MakeAnalysisTable- make a usual table of mineralchemical \
analyses (wt.% and formula units) *)
(* This top-cell must be run once before any example can be \
performed. *)

(* Define the directory, where the PET-files reside (e.g. C:\Eigene \
Dateien\Pet) and load PET. *)
$PetDirectory = "C:\Eigene Dateien\Pet";
SetDirectory[$PetDirectory];
DeclarePackage["DEFDAT`", {"Dataset"}];
Dataset[Dataset -> [COLOR="Red"]B88[/COLOR]];





另一个相关的“DEFDAT”:
(* Name: DEFDAT`

(* Summary: this package declares various PET-functions *)

BeginPackage["DEFDAT`"]

Dataset::usage = "Dataset[Dataset-> ...] selects the thermodynamic dataset to be used.\n\n
The following data sets are available, loaded with:\n\n
Berman (1988) J Petrol 29:445-522 Dataset[Dataset -> B88]\n
Holland & Powell (1998) J metam Geol 16:309-343 Dataset[Dataset -> HP31], or\n
Dataset[Dataset -> HP32]\n
Gottschalk (1997) Eur J Mineral 9:175-223 Dataset[Dataset -> G97]\n\n
See G::usage for more details.\n
\"31\" or \"32\" following \"HP\" indicates that the thermodynamic data have been\n
converted from THERMOCALC-versions 3.1 or 3.2 of Holland & Powell respectively.\n
When you start PET, a subdirectory \"/work\" is created by default, from which all user-files\n
(e.g. mineralchemical data files) are read and all files produced by PET are written to.\n
To create a new subdirectory for that purpose, you can use the option:\n
WorkDirectory -> \"/directory_name\"\n
Example: Dataset[Dataset -> [B]B88[/B], WorkDirectory -> \"sample_xy\"]\n
This loads PET with the Berman data set and reads/writes all user files from/to the\n
subdirectory named \"sample_xy\".\n

我想请问各位高手是不是Mathematica不能识别这个调用？要怎样解决呢，不知道描述的是否清楚。。
