Thanks for the update. Looks nice.

"o" key will open a file selection dialog.

Couldn't an "Open" button be added somewhere on top or bottom of the left panel?

 

I dropped some random files to do some tests, and when I change the type for any of those files to "Hard Interlace Picture" (not being a file of that format), the header for the right pannel dissappears. Then, it is not possible to select other type for the file. Again, it could be a way to return to the default file format.

 

It is still missing an alternative way to display Font files, in order to use ANTIC 4 four color characters (2 bits per pixel similar to Graphics 7 Image, but on single scan lines).

 

For images without a defined palette, it could be great to use default color palette in addition to the grey scale (selectable?).

 

On ATASCII text modes, the extra top and bottom empty lines sometimes disturbs me...

They are the same than Atari BASIC lists, but with extensions. You must also add 0x0D type when checking a[j] to extract an hex constant from 6 byte data stored as a BCD number. For string constants, you must duplicate the contained double quotes. I think there was also a check for variable numbers for more than 128 of them (probably token 0x54 is related).

 

I hope this helps...

Hi and thanks for adding TBXL.

 

It shouldn't be showing the "ESC" character at the end of these dashed lines.

Clearly, it is interpreting the chr(155) I included in my list as a displayed character, but it actually acts as a line feed. I wrote that code about 15 years ago, and I'm not sure how I managed it. I guess that it can be removed from the list for this tool.

 

BTW, my statements list also includes the spaces for both Atari and TurboBasic reserved words, in order to manage them with a single algorithm, without checking if it is standard or extended (token id greater than 56). A single parser for both syntaxes, without the need of to add a single whitespace where it is required.

 

Oh, in the file type, it should now say something like "Atari BASIC/TurboBasic XL".

Should add indenting for tokenized TBXL listings.

 

The above listing should look like this.

All of these structures use indenting:

 

REPEAT / UNTIL

 

WHILE / WEND

 

DO / LOOP

 

IF / ELSE / ENDIF

 

PROC / ENDPROC

To support variables > 127, you need to add the "0" token at line 1624, like this (from line 1621):

 

                    case 0x16: // EOL
                        k = end;
                        break;
                    case 0x00: // variable > 127
                        txt = b.variable_names[a[j+k++]];
                        break;
                    default: {
                        var txt;
                        if (op & 0x80)
                            txt = b.variable_names[op&0x7F];
                        else {

Have Fun!

That is not very practical, because that should require a logic parser, not just a detokenizer. The structures don't look good when lines are combined using ":". I think this should remains the same, just like after an "*L-" statement.

It certainly looks better to have indenting for listings like above.

 

Maybe he could have it as an option -- just as it's an option in TBXL.

Attached has the three changes for TBXL files:

- Adds support for more than 128 variables,

- Removes the EOL at the end of "--",

- Adds indentation.

 

As @vitoco said, for this you need to parse the code a little, to detect "IF" without "THEN". I used the same algorithm as the original TBXL.

 

Have Fun!

This version adds a toggle to show indented or plain listing.

And also fixes a bug with IF and comparisons to empty strings:  IF A$="" THEN  was indented.

Oops!

 

I got an out of memory error after dropping a random JPG file and changing from "Raw Data" (the default for an unknown extension) to a "Load and Go Executable".

 

I had not taken a look into the sources but I guess that the tool is not checking for invalid XEX binary pointers for blocks, for example, a lower end memory address than the start one.

Great tool. Can't believe all the updates this week.

While you're at it, can ATX and PRO images be supported?

Thanks, but out of the images I tested it against, it only works for Cribbage.

 

Perhaps it is easier to just let the user enter the starting sector of the directory. The VTOC has for read-only access no relevance.

 

Find attached some images with varying starts of the directory (VTOC is mostly the sector before the directory).

It also does not work for DOS 2.0 DD disks. It seems that DOS 2.0D only uses the first 128 bytes of each directory sector.

This version does a full scan of the disk looking for directories and works for the above.

It also scans for files with no legitimate directory entries: kind of a poor man's unerase.

The Atari Accountant disk had garbage in the directory: sector start position and sized were mangled. an attempt at copy protection perhaps?

This new version recovers these files despite the broken directories.

 

many thanks for the help.

Yes, perhaps.

But most important: It works. :)

... also on a DD disk with a correct directory.
