To judge from the subject header, Morris's question has to do with
programming technique, as opposed to manual text entry. In other
words, in XPL, how do you initialize a counter, then increment it
and insert (hard-code) the counter number in text at the desired
cursor position? Here's a basic schema, with gaps for (1) a
conditional test to prevent the counter from incrementing ad
infinitum (i.e., to avoid an endless loop), and (2) code to position
the cursor before writing the counter:

;*;       Initialize counter
;*;        Begin loop
;*; <=========== IF okay to continue...
+1>;*;   Increment counter
;*;        Write counter
;*;        Loop back
;*;       Else Exit

Here's a working example that writes five counters at the cursor
position. The IF test is, simply, is the counter less than 5? If
so, increment and continue; else EXit.
