Very often you'll need to convert ascii to hex or decimal numbers and back. An ascii table is THE tool you'll need for that. Here is one.

If you need the hex value of 'H', look for H. It's in column $4x and row $x8. 'H' = $48 or 0x48. Other way around: You need to know what 0x69 is when shown as a character. Column $6x, row $x9: 'i'

The "ctrl" column contains the control characters in short form. The real name can be found further down on this page in a seperate table.

We're working on a printable version of this... Most probably we'll have to divide the table by three or so and fill three pages. One won't be enough for all this...
