Compile time is the duration it takes to compile a module.
Pascal modules can be be compiled in a very short time.
A Hello, World program can be compiled in less than half a second.
The FPC reports the time it took if the command line option
-vi (show general information) is set.
Compile-time refers to the period when a Pascal module is being compiled. Thus “Compile-time information” refers to information known by the compiler during compilation. Examples of such information available at compile-time include compiler switches, values of identifiers defined as const, quoted strings, and the actual text of the program.
Information available at compile-time is usually more efficient for the program as initialization of constants and value-defined variables can be done once, when the program is compiled, as opposed to doing so at runtime each time the program is started.
