PRO/II allows you to custom-build your process environment, define your own stream property and units of measure lists, or choose your favorite editor or viewer. It's all under the Options menu, described in this section.
Stream Property Lists
Select Stream Property Lists from the Options menu to create and main-tain property lists for STREAM PROPERTY TABLES. Within the Define Property List dialog box, you can create, modify, delete, and save prop-erty lists. You can also:
■ Reorder the property entries in a selected list.
■ Change the format of the displayed data values.
■ Change the overall appearance of the table by adding blank lines or text, altering the line, border, and/or cell character widths.
The data formats originate from the C programming language. Table 26 shows more details. Since PRO/II stores new property lists unless you explicitly delete them, you can use the same property list in more than one simulation.
Your custom table will appear in the Property List to be Used list when you add and open a STREAMPROPERTYTABLE on the flowsheet.
Units of Measure Lists
The Units of Measure (UOM) library contains three default sets:
English, Metric, and SI. You can create, copy, edit, rename, or delete UOM sets for the Units of Measure library. Clicking allows you to choose English, Metric, or SI as a basis and modify the set to fit your requirements. PRO/II stores user-defined UOM sets in the library.
You can specify any set as a global default or as a simulation default for either input data or output reports. The global default set remains in effect for future PRO/II sessions, whereas a simulation default only

affects the current simulation and is selected by clicking the UOM tool-bar button.
Drawing Defaults
You can set three types of drawing defaults:
■ General
■ Unit Display
■ Stream Display.
General Drawing Defaults include zoom increments, pan increments, paper size, the unit icon palette, and other miscellaneous features, including a check box to prompt for unit and stream names as they are created. Figure 52 shows the General Drawing Defaults dialog box.
Figure 52:
General Drawing Defaults Dialog Box
Choosing Unit Display from the Drawing Defaults menu gives you the Unit Display dialog box. In this dialog box, you can select the type of unit operation you want to change and enter any changes for the label format and starting number. For certain operations, you have a choice of icon symbol. These changes affect any unit operation that you subse-quently place on the PFD. However, they will not change existing units.
Figure 53 shows the Unit Display dialog box with the SIMPLE HEAT EXCHANGER icon selected. For this unit operation, you have a choice of five icons.
To change the style of an individual unit on the PFD, right-click on the unit to access the unit menu, and choose Display. A similar dialog box will appear.
Figure 53:
Unit Display Dialog Box
Choosing Stream Display from the Drawing Defaults menu brings up the Stream Style dialog box shown in Figure 54. This dialog box allows you to change various aspects of the stream style.
Alternatively, you can change the number or label of an individual stream in a Stream Data dialog box without altering the ongoing num-bering sequence.

Simulation Defaults
You can set five types of Simulation Defaults:
■ Problem Description
■ Units of Measure
■ Thermodynamic System
■ Assay Characterization
■ Autosave
Select Problem Description to enter a user name, project identifier, site, site, date, and problem description that will be included each time you open a new simulation. This feature is useful for defining problem description items that don't change frequently.
As previously mentioned, the Units of Measure option allows you to set the default units of measure for data input and the default set for output.
This feature allows you to match your company's measurement stan-dards. Note that English units are the startup default.
PRO/II does not have a default thermodynamic system. However, you can select a default method by selecting the Thermodynamic System option.
Select Assay Characterization allows you to set defaults for characteriz-ing your assay data. Again, you can match standard company procedures with this feature. Clicking will reset PRO/II to its orig-inal internal defaults.
Select Autosave to specify how frequent you want PRO/II to save your current work. This option is not active by default.
Other Options The Options menu also contains a series of miscellaneous tasks. Select the appropriate option to carry out the associated function:
■ Colors—change the default PRO/II colors, such as icon fill color, the flowsheet color, and the border colors for the different data types, as well as the border style and line width.
■ Editor—change the editor (such as Brief, Edit, or Notepad) that is used to display and print keyword input files and output reports. The default editor is the Programmer’s File Editor (PFE).
,
Note: This can be a dangerous option to set, as choosing an inappro-priate thermodynamic system will cause erroneous results.Restore Defaults
■ Viewer—change the default viewer used for displaying individual stream or unit output results; options are Editor, (HTML) Viewer, and Default Browser (such as Netscape Navigator or Microsoft Internet Explorer).
■ Font—change the font, font style (bold, italic, etc.), and font size used for the palettes and the dialog box displays.
■ Plot Setup—add a new plot driver or to change the default plot driver.
■ New File on Startup—use this toggle option (✓) to automatically cre-ate a new file upon startup of PRO/II.
■ Welcome to PROVISION Window—use this toggle option (✓) to bypass or restore the welcome message for future PRO/II sessions.
■ Suppress Run Warnings—use this toggle (✓) to suppress the appear-ance of the Status dialog box so that the run continues without inter-ruption.
■ Maximize on New File—use this toggle (✓) to maximize a new file when created.
