How to Use the TYPE() Function

ID: Q88975

The information in this article applies to:

Microsoft FoxBASE+ for MS-DOS, versions 1.21 and 2.0
Microsoft FoxPro for MS-DOS, versions 1.0, 1.01, 1.02, 2.0, 2.5, and 2.5a
Microsoft FoxPro for Windows, versions 2.5 and 2.5a

The TYPE() function returns the data type code for a specified expression. Quotation marks are required around the specified variable or field name used.

The following examples demonstrate the use of the TYPE() function:

Example 1

   x=1
   ? TYPE("x")   && returns N

Example 2

   x="TEST"
   ? TYPE("x")   && returns C

Example 3

   x=DATE()
   ? TYPE("x")   && returns D

Example 4

   x=1
   ? TYPE(x)     && returns an ERROR

Example 5

   x="TEST"
   ? TYPE(x)     && returns U

Example 4 returns an error because FoxPro tries to use x as a subscript. The last example returns U because the variable TEST does not exist.
