How to install it

What to send to the palmtop saves 3.5 KB

These are the files you need. You can send them from the package contents below.

  • steam97.exm → A:\SOFT aplicación del System Manager 54.0 KB
  • steam97.icn → A:\SOFT icono, junto a su aplicación 200 B

No need to put steam97e.txt: they are manuals, source code or supporting material. Read them here and save 3.5 KB on a 1 MB disk.

Steps
  1. Copy steam97.exm to A:\SOFT. It is a System Manager application: register it in App Manager with F2 (Add), giving the full path (for example A:\SOFT\steam97.exm).
  2. The 200LX takes 8 EXM applications at most. Check with F8 (List) in App Manager: an asterisk in the Status column means the quota is full and you will need MoreEXM.
  3. The .ICN files are icons: they go in the same folder as their application.

Derived from the package contents and the 200LX conventions. It installs to A: on purpose: C: is a RAM disk and every byte there is memory taken from the system.

The author's instructions
----- Installation
This archive includes following files.
    STEAM97E.TXT  ..... This file
    STEAM97.EXM   ..... Executable file
    STEAM97.ICN   ..... Icon file

Unzip .EXM and .ICN files, and register STEAM97.EXM to the System Manager.
At the first execution, STEAM97 automatically creates a STEAM97.ENV file
in A:\_DAT directory.  If you don't have a: drive, then c:\_DAT is assigned
instead.


----- How to Use
1.Enter temperature and pressure, then press [F10].  Steam/water properties
  then be displayed.
  The possible range of input value is displayed by pressing [F1] key.
  The unit system of input values is assumed that now on display.

2.You can select the unit sets by checking [UnitSet] menu in the menu bar.
  When selecting multiple sets, you can change the unit set by [F9] key,
  at any time.
  At the first execution of the program, SI(C) and Metric are selected.

3.To calculate the saturation, enter either temperature or pressure and the
  other field should leave blank.  In this case, the pressure or temperature
  must be below the critical point.

4.To calculate wet steam, enter temperature and quality or pressure and
  quality.  The quality (%wetness) is identified by a suffix 'x' or 'X' at
  the other field.
  ex) Temp[180         ]  Press[2.5x       ]   <- 180deg-C and 2.5% quality

5.To calculate properties from pressure and enthalpy, enter the enthalpy data
  at Temp field.  The enthalpy is identified by a suffix 'h' or 'H'.
  ex) Temp[800h        ]  Press[120        ]   <- 800kcal/kg and 120kg/cm2a

  ** Caution **
  If the entered enthalpy and pressure belongs region 3, a dialog will
  appear to confirm wheter continue or cancel calculation because it will
  take several minutes to finish. During the calculation, you can't switch
…

Send to my palmtop

The palmtop must be waiting before you press the button, or the transfer will fail. It is the palmtop that announces it is ready, not the other way round.
