Context.Connection.Socket.WriteInteger() not available?

On the old version of Indy 10, I noticed that WriteInteger wasn't available - a bit of a pain when i was trying to send file sizes before sending files!

On this version (10.6.3.3) there is still no WriteInteger() procedure available yet it was in Indy 9 (and 8 I think too).

How can I get around this please?

Thanks
