ASP Ombudsman 

Steam Properties is produced by Taftan Data, a member of the 
Association of Shareware Professionals (ASP).  ASP wants to make sure 
that the shareware principle works for you. If you are unable to 
resolve a shareware-related problem with an ASP member by contacting 
the member directly, ASP may be able to help. The ASP Ombudsman can 
help you resolve a dispute or problem with an ASP member, but does 
not provide technical support for members' products.  Please write to 
the ASP Ombudsman at 545 Grover Road, Muskegon, MI USA 49442-9427,

3-How to install Steam Properties?

Steam Properties is a Windows program. In order to install the program:

1) Copy all the files mentioned above to a suitable directory
2) In Windows choose: File, New and then select "steampro.exe"

If you wish to test the program in diskette directly without installation, 
the diskette should not be write protected. Steam Properties saves the 
latest changes to input fields and default units and whenever you start 
you can begin where you finished last time. 

---------------------------------------------------------------------------
4-How to install DLL version of Steam Properties? 
  (registered version only!)

DLL version of Steam Properties is a Windows program. In order to install
the program:

1) Copy all the files mentioned above to a suitable directory.
   This step is not necessary if you have already installed steam 
   properties.
2) In Windows choose: File, New and then select "dllsetup.exe"
3) Define the complete path of DLL version in your "AUTOEXEC.BAT"
   i.e. if you have copied Steam Properties on your C drive in a 
   subdirectory called \MYDATA\STEAM12 you should add this line
   
   SET STEAMPRO=C:\MYDATA\STEAM12

   into your AUTOEXEC.BAT file.

After next reboot of your system DLL version is properly installed and 
you can run "dllsetup.exe" to choose your favorite units for inputs and
outputs.
If you wish to test the program in diskette directly without installation, 
the diskette should not be write protected. DLL setup saves the 
latest changes to the default units.

Attention! DLL version needs that the following files exist in the same
directory:
           DEFAULT.CFG
           STEAMP.DAT
           STEAMPT.DAT
           STEAMT.DAT
           STEAM.DLL      
           DLLSETUP.EXE   

Now DLL version can be used in your application. All major spreadsheet and
database programs support integration of functions defined in DLLs. 
The user manual of your spreadsheet or database program describes if you can
use DLLs and how you "register functions" and call them. The functions 
inside the DLL are following:

    Function   Inputs                          Output
 1  STMPT      Pressure                        Saturation Temperature 
 2  STMTP      Temperature                     Saturation Pressure 
 3  STMTQH     Temperature & Dryness fraction  Enthalpy
 4  STMTQS     Temperature & Dryness fraction  Entropy
 5  STMTQV     Temperature & Dryness fraction  Specific Volume
 6  STMPQH     Pressure & Dryness fraction     Enthalpy
 7  STMPQS     Pressure & Dryness fraction     Entropy
 8  STMPQV     Pressure & Dryness fraction     Specific Volume
 9  STMPTH     Pressure & Temperature          Enthalpy
10  STMPTS     Pressure & Temperature          Entropy
11  STMPTV     Pressure & Temperature          Specific Volume 
12  STMPHT     Pressure & Enthalpy             Temperature
13  STMPHS     Pressure & Enthalpy             Entropy
14  STMPHV     Pressure & Enthalpy             Specific Volume
15  STMPHQ     Pressure & Enthalpy             Dryness fraction
16  STMPST     Pressure & Entropy              Temperature
17  STMPSH     Pressure & Entropy              Enthalpy
18  STMPSV     Pressure & Entropy              Specific Volume
19  STMPSQ     Pressure & Entropy              Dryness fraction
20  STMPVT     Pressure & Specific Volume      Temperature
21  STMPVH     Pressure & Specific Volume      Enthalpy
22  STMPVS     Pressure & Specific volume      Entropy
23  STMPVQ     Pressure & Specific volume      Dryness fraction

5-How to call functions inside DLL version of Steam Properties from 
  MS EXCEL?

Functions inside a DLL can be made accessible by using "register" function
in MS EXCEL. For example if you need to calculate the specific enthalpy of 
steam and you know the absolute pressure and temperature you should use 
STMPTH which needs two inputs (P,T) and has one output i.e. h.
You assign a cell e.g. A1 this value:

 REGISTER("C:\MYDATA\STEAM12\STEAM.DLL";"STMPTH";"EBB")
or
 REGISTER("C:\MYDATA\STEAM12\STEAM.DLL";"STMPTH";"EBB!")

where,

 C:\MYDATA\STEAM12\STEAM.DLL (is the location of STEAM.DLL on your drive)
                             (Module_text in MS EXCEL                   )

 STMPTH     (is the name of the function you intend to use)
            (Procedure_text in MS EXCEL                   )
 
 EBB        (specifies that the function needs two input of double type and) 
            (returns a pointer to a double type                            )
            (Type_text in MS EXCEL                                         )

 EBB!       (works in the same way as EBB except that each time you change) 
            (the inputs to the function MS EXCEL automatically updates the)
            (output                                                       )
            (Type_text in MS EXCEL                                        )

You will register each function only once, but you can call it as many times 
as you wish. Here is an example on how you use "CALL":

 CALL("A1";"20";"100")

Where,
 
 A1  is the cell where you registered the function
 20  is the first input; in this case pressure
 100 is the second input; in this case temperature

Input and output parameters will be in default units. The default units can
be selected by running "dllsetup.exe".
The name of the functions and Type_text for using with "REGISTER" are:

    Function   Type_text
 1  STMPT      EB   or  EB! 
 2  STMTP      EB   or  EB!  
 3  STMTQH     EBB  or  EBB!
 4  STMTQS     EBB  or  EBB!
 5  STMTQV     EBB  or  EBB!
 6  STMPQH     EBB  or  EBB!
 7  STMPQS     EBB  or  EBB!
 8  STMPQV     EBB  or  EBB!
 9  STMPTH     EBB  or  EBB!
10  STMPTS     EBB  or  EBB!
11  STMPTV     EBB  or  EBB! 
12  STMPHT     EBB  or  EBB!
13  STMPHS     EBB  or  EBB!
14  STMPHV     EBB  or  EBB!
15  STMPHQ     EBB  or  EBB!
16  STMPST     EBB  or  EBB!
17  STMPSH     EBB  or  EBB!
18  STMPSV     EBB  or  EBB!
19  STMPSQ     EBB  or  EBB!
20  STMPVT     EBB  or  EBB!
21  STMPVH     EBB  or  EBB!
22  STMPVS     EBB  or  EBB!
23  STMPVQ     EBB  or  EBB!
