The Color Disk EDTASM assembler has the option of writing a symbol table to the end of binaries it produces. You enable the feature by including the /WS switch during assembly to disk. The symbol table can be used by the stand alone ZBUG debugger.

Invoking the switch will add extra data after the LOADM post-amble. Here is how that data is formatted. First is the header. This is always 5 bytes in length.

.tg {border-collapse:collapse;border-spacing:0;} .tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; overflow:hidden;padding:10px 5px;word-break:normal;} .tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;} .tg .tg-0lax{text-align:left;vertical-align:top}

Length	Example Value	Description
1 Byte	01	Seems to be constant
2 Bytes	0019	The total length of the symbols and values, plus one
2 Bytes	0000	Seems to be constant

Next you will find a table entry for each symbol and value pair.

.tg {border-collapse:collapse;border-spacing:0;} .tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; overflow:hidden;padding:10px 5px;word-break:normal;} .tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;} .tg .tg-0lax{text-align:left;vertical-align:top}

Length	Example Value	Description
1 Byte	84	Length of the symbol text, with the high bit set
n Bytes	DONE	Symbol name, ASCII encoded
2 Bytes	0004	Symbol value

And finally is the footer. a single constant byte:

.tg {border-collapse:collapse;border-spacing:0;} .tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; overflow:hidden;padding:10px 5px;word-break:normal;} .tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;} .tg .tg-0lax{text-align:left;vertical-align:top}

Length	Example Value	Description
1 Byte	0	Seems to be constant

It should be noted the Assembler and ZBUG pair can only handle symbols with a maximum of six characters.
