Syntax

string.Extract(StartIndex: Integer, Length: Integer) : String

where StartIndex is the index (0 or 1) of the substring first character and Length the sub string length.

Example

Message (Responsible.Extract(2,2))

Sample

Length()

Syntax

string.Length(Integer

Sample

ToString()  

Converts an integer into a string. 

Syntax

ReplaceSubText()

Syntax

ReplaceSubText(InputString: String, SubStringToBeReplaced: String, ReplacingSubString: String): String

Arguments 2 and 3 can be specified either with their parameters names or with the string itself between quotes.

ToUpper()  

Changes all lower-case letters of a string to upper-case.

Syntax

ToUpper(StringTobeConverted: String): String

where StringTobeConverted is name of the string type parameter.

Sample

KwrString.CATPart

BuildMessageNLS

Enables you to send messages or ask questions through the Message and Question functions in the language of your choice. The BuildMessageNLS function can build a NLS message (a message in a given language) by finding it in a CATXXX.CATNls file.

Note that this function is useful when used together with the Message and Question functions. For more information about these 2 functions, see the Knowledge Advisor User's Guide.

Syntax

BuildMessageNLS(MessageCatalog:String, MessageKey: String, argument: Literal, ...):String

where:

• MessageCatalog:String is the name of the CATXXX.CATNls file where we will find the NLS message (it is the CATXXX name without the CATNls extension).
• MessageKey: String is the key name in this catalog
• argument: Literal, ... are values that will be replaced in the message.

Example

The KwrCATCatalog.CATNls file contains the following text.
 

Zero, One and Two are the messages. The first message has no arguments, the second has 1 argument, the third, 2 arguments.

To display those messages in a Knowledge Advisor rule for example, enter the following rule body:
 

OR

OR

If the function does not find the key or the .NLS catalog, it will return an empty string. If there are too many parameters compared to the number of arguments of the message, the parameters will be ignored. If there are too few parameters compared to the number of arguments of the message, the parameters will be replaced with a "???" string. Note that the .NLS file is to be stored in the runtime view (in the msgcatalog directory)
