'''ACiDDraw COM file''' is a format for [[ANSI Art]]-style character graphics. It is associated with ACiDDraw, an ANSI Art editor for DOS.

It is in the form of a [[DOS executable (.com)|DOS .COM]] file that, when executed, displays the graphics in a full-screen viewer.

== Discussion ==
There are apparently just two freely-distributable versions of ACiDDraw that support COM format: 1.20 and 1.25r. But, presumably, there is at least one registered edition of v1.20 that creates different files, and which hasn't been studied.

== Format details ==
Some files end with a [[SAUCE]] record.

== Identification ==
Let ''B'' be the byte pattern:

 b8 03 00 cd 10 b4 01 b9 00 20 cd 10 e8 cb ff ba 
 ?? ?? 90 e8 e5 ff 3d 1b 01 75 03 e9 bd 00 3d 00
 ...

COM files made by v1.20-unregistered are observed to start with bytes {{magic|e9 9f 00 19 00}}, and have ''B'' at offset 162. The text "{{magic|Created in an UNREGISTERED ACiDDRAW v1.2!}}" appears at offset 6, though in many files, it's been modified.

COM files made by v1.25r start with {{magic|eb 42 90 19 00}}, and have ''B'' at offset 68.
Text "{{magic|Created by ACiDDRAW v1.2}}" appears at offset 6.

More generally, ''B'' appears at the target of the relative JMP instruction at the beginning of the file ([<code>eb xx</code>] or [<code>e9 xx xx</code>]).
