Function result	String	Text of the error

Description

error is the integer number of the error.

Example

The following is an example of an ErrorCheck routine that will display an alert message explaining the cause of an error.

  `Method: ERRCHECK ("Command Name"; Error# ) -> True/False

 C_TEXT(vErrorMsg)

 $Command:=$1

 $Error:=$2

 $Result:=True

 If($Error#0)

    $Result:=False

    vErrorMsg:=IT_ErrorText($Error)

    ALERT("ERROR -- "+Char(13)+"Command: "+$Command+Char(13)+"Error Code:"+String($Error)

    +Char(13)+"Description: "+vErrorMsg)

 End if

 $0:=$Result
