This debugger was designed as a companion for Sozobon C and therefore it understands its symbol table format, which was inherited from Alcyon compiler. The version for which this document was written also supports MWC — currently the official Atari development compiler. It will cooperate also with the ST version of GNU compiler gcc. If you happen to have an older version of gcc loader it may be necessary for you to get your hands dirty in a source code. Even better idea would be to update your compiler. The current gcc loader can optionally produce symbol tables in ``GST format'' where symbols can be up to twenty two characters long. Version 1.3 of szadb will correctly recognize and use that format as well.
