FILE TYPES.
▀▀▀▀▀▀▀▀▀▀▀
Files are described by a name of up to 8 characters plus an extension
name of up to 3 characters. Whereas the file name is selected by the
user, the extension name is frequently defined by the system in use.
Some typical extension names relevant to MS-DOS and Turbo Pascal are:
.BAK Backup source file - a resaved file automatically saves the original as a .BAK file.
.BAT Batch file containing a sequence of MS-DOS command lines.
.BGI Borland Graphics Interface file, for screen display.
.COM Compiled file, which is an executable file from MS-DOS.
.EXE Executable file from MS-DOS.
.HLP Help file.
.PAS Pascal source code file.
.SYS System file used by MS-DOS.
.TPL Turbo Pascal Library File.
.TPU Turbo Pascal Unit file.
.TXT Text file in ASCII format.
Source code, written in a high level language, such as Pascal, is converted
into Object code (machine language) by a Compiler. Whereas Turbo Pascal,
version 3, created .COM files at compilation, version 6.0 now creates .EXE
files.
