VBScript in a Nutshell, 2nd Edition

Name

Execute Statement

Syntax

Execute statement

statement

Use: Required

Data Type: String expression

A string expression containing one or more statements for execution.

Description

Executes one or more statements.

Rules at a Glance

• statement must evaluate to a string that contains one or more executable statements. An executable statement is any call to a user-defined procedure or function, or any intrinsic VBScript command.

• You can put multiple statements in the expression; separate them with colons.

• You can also separate the arguments with embedded line breaks.

• If statement includes an equal sign, it is interpreted as an assignment rather than an evaluation. For example, x = 3 assigns the value 3 to the variable x, rather than comparing the value of the variable x with 3.

• In VBScript, a program fragment such as x=3 can be interpreted as both an assignment statement (assigning the value 3 to the variable x) or as a comparison expression (for example If x = 3 Then...) The Execute and ExecuteGlobal statements always treat strings of the form a = b as assignment statements. Use Eval to interpret strings of this form as expressions.

Example

The following is a corrected version of an example appearing in online help that appears to do nothing. In this case, the Execute statement is used to execute a procedure named Proc2, and the entire source code for the procedure is also stored to the string S that is passed to the Execute statement:

dim S S = "Proc2 : " S = S & "Sub Proc2 : " S = S & "Dim x : " ...
