String Expressions

Kalipso - Developing - Form - Expressions - String Expressions

String Expressions return a <string>, and each part of the expression is evaluated as a string.

When editing an Expression of this type, you have available Functions and all the Kalipso objects from where you can retrieve values (Global Variables, Controls and Local Variables). To use any of these items you just have to double-click it and it will be automatically added to the Expression.

Examples:

Consider that the value of Input "iProduct" is 1020393.

• Example 1

"Product with code <" + CTRL(iProduct) + "> not found!" Result = Product with code <1020393> not found!

• Example 2

"The result of 1 + 2 is " + "1" + "2" + "." Result = The result of 1 + 2 is 12

• Example 3

"The result of 1 + 2 is " + NumToString(1 + 2) + "." Result = The result of 1 + 2 is 3

There are multiple ways to add ENTERs in string expressions, including inside the string itself.

Check the next 3 example:

Example1: "123" + ENTER + "456"

Example2: "123" + CR + LF + "456"

Example3: "123

456"
