Format object help required (SOLVED)

Peter Verkaik

Attached are my Format object and Format test program.
I load the test program into a spin stamp and output strings
via the propclip.

The mainloop is
· repeat
'··· fmt.sprintf(buffer,string("%c"),"Z")
··· fmt.sprintf(buffer,string("%s"),string("ABCD"))
'··· fmt.sprintf(buffer,string("%d"),16)
'··· fmt.sprintf(buffer,string("%i"),16)
'··· fmt.sprintf(buffer,string("%b"),16)
'··· fmt.sprintf(buffer,string("%o"),16)
'··· fmt.sprintf(buffer,string("%u"),16)
'··· fmt.sprintf(buffer,string("%x"),16)
··· debugHex2(buffer)
··· waitcnt(clkfreq / 1000 * 100 + cnt)

The idea is to enable just one of the sprintf statements.
For %c I get 5A (hexvalue of "Z") in a rapid tempo.
For %s I get 41424344, but there is quite a delay between successive outputs.
All the other output nothing. It looks Format.bprintf never returns.
Strange, as this is the exact code I use on the Javelin and there it works.

Can anybody spot any (obvious) error? As this is my first propeller project it is quite
possible I did something wrong with the pointers.

I used <= and >= where I should have used =< and =>.
The attached Format.spin is updated.
Unfortunately, the issue still stands.

I got it cracked.
For most calls I needed to use @buffer instead of buffer alone.
Coming from C where the array name is the address and equal to &arrayname[noparse][[/noparse]0],
in Spin the array name by itself equals arrayname[noparse][[/noparse]0]. Not the best of choice
but so be it.

Attached are the updated object and test program.

Final update (I believe this to be bugfree).
Added test for sscanf and documentation for sscanf and sprintf.
Added support for \\, \t, \n, \r in printf format string.
