Include file

WebAPI.bdh

Syntax

WebTelnetSetRecordString( in hHandle : number,
  in sFieldname : string, 
  in sValue : string,
  in iLen : number optional ) : boolean;

Return value

true if the operation was successful
false otherwise

Parameter	Description
hHandle	Valid handle to a data record that is being prepared, from a previous WebTelnetSendRecordPrepare command.
sFieldname	Name of the field. Must match one of the field names embedded in the data record previously specified in a WebTelnetSendRecordPrepare command, in the format: “`%s###`”, such as “`%s1`”.
sValue	Value to be assigned to the field specified by sFieldname. This string value will be dynamically inserted in the data record when it is transmitted to the terminal server.
iLen	Length of the value to insert (optional). If sValue is longer than iLen, it will be cut off at iLen. If not specified, the value is zero, meaning that sValue can be of any length.
