Description
Sets the string value for a key. If the key does not exist, then create the key and set its value. If the key already exists, then overwrite the value of this key. If more than one key with the same name already exists, then overwrite the value of the first key. Notice that the IgnoreCase property (true by default) determines whether the key name will be matched in a case-sensitive manner.

// Integer SetValueString ( string Key, string Value )
String ls_DeptName

JsonPackage ljp_Dept
ljp_Dept = Create JsonPackage
// Loads the JSON string to the JSONPackage object
ljp_Dept.loadstring( '{"dept_id":100, "dept_name":"R & D8", "dept_head_id":105}')
li_Return = ljp_Dept.SetValueString( "dept_name", "D & R" ) // Sets the value for dept_name
If li_Return = 1 Then
ls_DeptName = ljp_Dept.GetValueString( "dept_name" ) // Gets the value of dept_name
Else
// Prints the error message
End If
