meaning of hard coded

1. hard-coded By analogy with "hard-wired" Said of a data value or behaviour written directly into a program, possibly in multiple places, where it cannot be easily modified. There are several alternatives, depending on how often the value is likely to change. It may be replaced with a compile-time constant, such as a C "#define" macro, in which case a change will still require recompilation; or it may be read at run time from a profile, resource see de-rezz, or environment variable that a user can easily modify; or it may be read as part of the programs input data. To change something hard-coded requires recompilation if using a compiled language of course but, more seriously, it requires sufficient understanding of the implementation to be sure that the change will not introduce inconsistency and cause the program to fail. For example, "The line terminator is hard-coded as newline; who in their right mind would use anything else?" See magic number. [Jargon File]
