<p>Needed in a couple of places</p> <p><b>New page</b></p><div>A '''symbol table''' is a data structure found in [[binary]] [[file]]s of various sorts, such as [[relocatable binary]] files (for example, [[UNIX a.out file]]s). It consists of an array of elements ('entries'), each of which contains, at a minimum:<br /> <br /> * a symbol name<br /> * the symbol's value (usually an [[address]])<br /> <br /> Symbol table entries in relocatable binary files also usually contain other meta-information about the symbol - e.g. whether the symbol is defined (in the file), or it is an un-defined' [[external]] [[Scope|global]] reference (which will have to be discovered and 'resolved' - i.e. assigned the appropriate value - during the [[linking]] process), etc.<br /> <br /> In addition to relocatable binary files, symbol tables are often found in [[object code|executable binary]] files, for use by a [[debugger]].<br /> <br /> Early on, the symbol names in such symbol tables were stored in representations such as [[RADIX-50]], [[SIXBIT]] and [[SQUOZE]], to absolutely minimize the amount of space needed to hold them (especially in the days of [[core memory]], when space was at a premium). Now, [[ASCII]] is usually used.<br /> <br /> [[Category: Software Basics]]</div>
