Automatic Type Conversion
DataFlex supports automatic type conversion among variables and tokens of most of the DataFlex simple types (Integer, Number, Real, etc.). Examples of DataFlex type conversion are:
Integer iTest
Move "123" To iTest
In the above example, an integer variable is declared, and it is assigned a string token "123". The result is that the integer 123 is stored into the integer variable. However, the following example will generate a runtime error.
Integer iTest
Move "XX123" To iTest
The reason for the error is that DataFlex is unable to interpret the string "XX123" as an integer.
Further examples of automatic type conversion are:
Number nTest
Integer iTest
String sTest
Date dTest
Move 2.001e3 To nTest // 2001.0 is stored in nTest
Move nTest To iTest // 2001 is stored in iTest
Move 01/01/2001 To dTest
Move dTest To sTest // "01/01/2001" is stored in sTest
