Batch Script - String Interpolation


Advertisements

String interpolation is a way to construct a new String value from a mix of constants, variables, literals, and expressions by including their values inside a string literal.

In DOS scripting, the string interpolation can be done using the set command and lining up the numeric defined variables or any other literals in one line when using the set command.

The following example shows how a string interpolation can be done with numeric values as well.

Example

@echo off 
SET a = Hello 
SET b = World 
SET /A d = 50 
SET c=%a% and %b% %d%
echo %c%

Output

The above command produces the following output.

Hello and World 50
