Tool Tips

* How can file import settings be saved in Weibull++ File Import Wizard Profiles?
Weibull++ 7s File Import Wizard allows you to specify how data from a Tab Delimited (*.txt), Comma Delimited (*.csv), Space Delimited (*.prn), Semicolon Delimited (*.smc) or Excel (*.xls) file will be converted and imported into a new Standard Folio. To use the utility, match each column of data from the original file to a column available in Weibull++ Standard Folios by selecting the column in the spreadsheet and then clicking a button. At least one column must be identified as a "Time Value" and columns containing data that you do not want to import can be marked "Ignore."

Once you have defined all of the columns that you wish to add, you can select Save Profile from the Tools menu or select (i.e. depress) the Save Profile button on the toolbar to save the current definitions for use the next time you activate the File Import Wizard. It is important to note that only one profile exists at a time. When you save a profile, the settings from any previous saved profile are overwritten.

You can clear the saved profile by selecting Clear Profile from the Tools menu or by de-selecting the Save Profile button on the toolbar. These two options work differently. If the Save Profile button is de-selected, no column definitions will be saved, so the next time the File Import Wizard is activated, all columns will return to the default setting of Ignore. The changes you have made during the current session are used for this session only. If Clear Profile is selected, all columns are immediately reset to the default setting of Ignore. Any changes you have made in the current File Import Wizard session will be lost and the next time the File Import Wizard is activated, all columns will be set to the default setting of Ignore.

* What is the difference between subcharts and subroutines in RENO?

When simulating a Flowchart, RENO executes all paths in the Flowchart before performing the next simulation. If you build a Flowchart that contains two unconnected paths, both will be executed during the simulation. If, however, a Flag Marker is in the starting position of a path, you can right-click it and select Execute On Call Only. This allows you to create subroutines within the current Flowchart that will be executed only if they are called by a Go to Flag.

Subroutines function differently from subcharts, in that any number of Go to Flags can call and use a single subroutine within the current Flowchart; on the other hand, if a subchart is called by multiple Subchart Blocks in the Flowchart, each subchart block uses a separate copy of the subchart. If the subchart has a Result Storage Block, that Result Storage Block will appear separately in the Simulation Results Explorer for each Subchart Block that called the subchart. In addition, a subroutine can interact with the rest of the Flowchart (e.g. by using Go to Flags in the subroutine), while a subchart cannot interact with its parent Flowchart other than by passing a value on its outgoing path(s).
