This function saves value b into the variable with name a . Before saving, a type conversion is carried out for b into the data type of the variable.

Parameters

Parameter	Description
a	Name of the variable. Important note: Use parameter type "Value" and select the desired variable from the list after clicking on the parameter field. Example: MY_VAR
b	Value to be saved.

Return value and further type conversions on field and node

The return value of the function is the saved value converted into the type of the variable. Important note: This function is normally only used to assign a value to a variable. The return value is not normally used to set the value of a field or to calculate whether a node should be entered. The effects on fields and nodes are only described here to explain any phenomena that may occur.

If the function is executed on a field, a further type conversion (type variable → type field) may occur, depending on the type of the field.

If the function is executed on a node, it is entered if value true is given as the result after a further type conversion (type variable → type "Boolean"):

Type of variable	Result
String, Blob	"true" if the text can be interpreted as a number and the condition for numerical values is fulfilled or if the text begins with a "t" or "T".
Numerical type (e.g. Integer)	"true" if the value is > 0.
Date type (Date, TimeStamp)	"true" if value after " 01.01.1970 00:00:00".
Boolean	No type conversion. true if the variable value is "true".

Example 1

Assume there is a variable "MY_VAR" with the type "String".

We execute the function with the following parameters.

Parameter a	Parameter b (parameter type "Value")
MY_VAR	sometext

The variable then contains the value sometext. A type conversion was not necessary as the variable has the type String.

If the function was executed on a field with type String, the field then has the value sometext. Note: A type conversion was not necessary because the field, like the variable, has the type String.

If the function was executed on a field with type Integer, the field then has the value 0. Note: A type conversion from String (sometext) to Integer (0) was performed.

If the function was executed on a node, the node is not entered. Note: A type conversion from String (sometext) to Boolean (false) was performed.

Example 2

Assume there is a variable "MY_VAR" with the type "String".

We execute the function with the following parameters.

Parameter a	Parameter b (parameter type "Value")
MY_VAR	text

The variable then contains the value text. A type conversion was not necessary as the variable has the type String.

If the function was executed on a field with type String, the field then has the value text. Note: A type conversion was not necessary because the field, like the variable, has the type String.

If the function was executed on a field with type Integer, the field then has the value 0. Note: A type conversion from String (text) to Integer (0) was performed.

If the function was executed on a node, the node is entered. Note: A type conversion from String (text) to Boolean (true) has been performed, see table above.

Example 3

Assume there is a variable "MY_VAR" with the type "Integer".

We execute the function with the following parameters.

Parameter a	Parameter b (parameter type" Value")
MY_VAR	text

The variable then contains the value 0. A type conversion from String (text) to Integer (0) was performed.

If the function was executed on a field with type String, the field then has the value 0. Note: A type conversion from Integer (0) to String (0) was performed.

If the function was executed on a field with type Integer, the field then has the value 0. Note: A type conversion was not necessary as the field, like the variable, has the type Integer.

If the function was executed on a node, the node is not entered. Note: A type conversion from Integer (0) to Boolean (false) was performed.
