Advantages of using READPRN and WRITEPRN

READPRN is generally preferable to READ. When the data values are regularly listed out in columns, READPRN brings the data into Mathcad in a readily accessible form. If some lines in a data file have more data values than others, data values may be missing. Use a text editor to replace the missing values with zeros before…

As described earlier in this chapter, Mathcad can import and export data files in formats recognized by other applications, including data files saved in spreadsheet programs. This is useful when you simply want to connect to a data file as opposed to the application in which it was created. For some work, however, you may need access to…

Importing data

Although you can use Mathcad as a tool for working with variable and function definitions, you can also use Mathcad to perform calculations on data. In order to do so, you first need to import the data into a Mathcad worksheet using either the File ReadlWrite component or the Input Table component. For a general discussion of components see…

Data Management

Many of Mathcad’s built-in functions and operators are useful for manipulating sets of data. Mathcad therefore provides special mechanisms for importing various types of data into a Mathcad worksheet. And, once you’ve worked with the data, Mathcad allows you to export the results you’ve generated. This chapter also discusses a group of Mathcad functions for reading and writing ASCII text…
