An easy one.
IDL> i=1951
IDL> plot,data,title='A plot of data for year '+string(i,format='(I4)')
The format parameter is optional, you could just use string(i).

thisTitle = 'Number ' + strcompress( string(x) )

Try this:
x = 5
thisTitle = 'Number ' + STRTRIM(x,2)
PLOT, FINDGEN(10), Title=thisTitle
