am I crazy or do printf() and sprintf() have no way to return, say, 0F instead of just F? I'm not a psychiatrist and never played one on TV so I can't judge if you're crazy or not. But check out this sniglet of code. `$ perl -e 'printf "%0.4x\n",128;' 0080` [download] Peter L.

Also, please see sprintf for a comprehensive discussion of the formatting specifiers available.	[reply]

Thanks to everyone who posted. I feel rather foolish. Somehow I was adding the zero for the padding but missing the number. I need more sleep.	[reply]
