Now I realized what's going on. I started with `67 00 00 00 ...`, yet I forgot about the leading zeros, it should be `00 00 00 67 00 00 00 ...`. Now it makes bit more sense.
But still a simple description of fields in p_batch_cs would speed things up for me greatly. -- Mgr. Jiří Činčura https://www.tabsoverspaces.com/ Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
