^number only prints the result out in decimal, according to the manual.
As for larger numbers than 32-bit, 64Tass is only available on 32-bit OSs. A 64-bit compiled version would probably work. For now, you'll just have to use two 32-bit variables for bigger hex strings. |

I'm using a -self compiled- version of 64Tass on OpenSuse 12.1 64bit, but seems that only 32bit numbers can be used...
In makefile
#CFLAGS = -O2 -march=i486 -mcpu=i486 -pipe
#CFLAGS = -Wall -O3 -march=i686 -pipe -fomit-frame-pointer -fno-exceptions
#CFLAGS = -Wall

I know that digging up old threads is not nice, but anyway just to close it up properly.
Use string formatting with hexadecimal output in some recent version:
.text "%04x" % (mylabel,)
And as of 1.51 I would not worry about running out of bits in integers on any platform. |

Just in these days i had this problem again using 1.5 (not 1.51!) and i solved using
.TEXT REPR (VALUE)
with
value=1234
.text "%04x" % (value,)
the compiler give a "type mismatch" error, that isn't if i use
.text "%04x" % (1234,)
instead.
Maybe it's fixed in 1.51...

Yes it didn't resolve identifiers in the formatting argument tuple in some versions of 1.50. This was so since tuples could contain identifiers and not just values.
When I noticed it the modifications for 1.51 were ongoing but it was unusable yet. So I worked it around it in my sources with dummy calculations like '(label+0, text.."")'.
Fixing it in 1.50 would have been a sort of a hack, but it's fixed now in 1.51 in a clean way now. |

I don't really like to dig up old threads, but anyway it's necessary for historical reasons.
Since then I realized that this percent formatting syntax was not really good idea as it's too easy to confuse with a normal modulo, especially when variables are used.
So it's gone now in r668. Instead formatting is done using a function with variable number of arguments:
.text format("%04x", mylabel)
If for whatever reason the arguments were contained in variable then the conversion looks like this:
.text format("%d: %s", *somelist)
I hope I don't have to update this thread again anytime soon. But one can never know, it's in development after all... |
