Let

 

Let>variable_name=value

 

Let is used to assign a value to a variable.

 

Where parameters are passed to commands, variables can also be passed.  Variables can also be embedded within a parameter by enclosing the variable name within % symbols.

 

Let can also be used to perform basic calculations, and to concatinate strings.  NB.  If you want to assign to a variable a string that already contains a + sign, add an extra + sign to avoid the two strings being concatinated.

 

The value can contain a complex expression:

 

Complex Expressions

 

The expression must be contained within curly braces "{" and "}".  String literals must be delimited with double quotes ("), e.g.:

"string".  Variables must be delimited with % symbols, e.g.: %VarA%.

 

Several types of operators and functions can be used with complex expressions.  For more details see Complex Expressions.

 

 

Examples

 

Let>name=freddy

Let>a=5

 

Let>path=c:\Program Files\

Run Program>%path%myapp.exe

 

Let>k=k+1

 

Let>A=60-4

 

Let>A=5*3

 

Let>F=75/32

 

Let>Forename=John

Let>Surname=Smith

Let>Name=%Forename% %Surname%

 

Name would now equal John Smith

 

Let>MyVal={Upper("WorLd")}

 

Let>MyVal={5 * 10 + 25}

 

Let>d={%a%+%b%*%c%-23}
