Procedure

 procedure Insert ( const InsertStr : string; var TargetStr : string; Position : Integer ) ;
Description

The TargetStr string characters from the Position character are moved right to make way for the InsertStr string.
 
The length of TargetStr is now the sum of the length of the two strings.
 
To insert into the start of TargetStr, set Position to 1 or less.
 
To append to the end of TargetStr, set Position after the last character of TargetStr.
