core dump | A core image of an executing program that is deposited in a file after the |
| program aborted execution. The core dump (also called a core file) |
| may contain information that is useful in debugging the aborted program. |
data dependence | The relationship that can obtain between the definition of data and its use. |
| The occurrence of a data dependence in a loop can prevent the optimizer |
| from parallelizing it. |
division by zero | The |
| divide a nonzero value by zero. |
driver | The component of the compiler that retains control throughout the entire |
| compilation process. |
Older, | |
programs | because they were presumably encoded and stored on punched cards. |
| Such programs are difficult to port and optimize. |

exception | A condition occurring during the execution of a program that may require |
| special handling to make further execution meaningful. Some exceptions |
| can be trapped by the system and handled within the program. |
extension | extension See filename extension and language extension. |
fast underflow | A hardware feature for handling underflow by substituting zero for the |
| operation that causes the underflow. |
file descriptor | An integer that is returned by certain |
| passed to others to provide access to a file. A file descriptor is similar to |
| Fortran’s logical unit number. When the Fortran 90 intrinsic FNUM is given |
| a logical unit number, it returns a file descriptor. |
filename extension | A sequence of characters that begins with a period (.) and is added to a |
| filename to indicate the function or contents of the file. See also language |
| extension.. |
The component of the compiler that parses source code and issues warning | |

integer overflow | An exception condition that occurs when attempting to use an integer to |
| represent a value that falls outside its range. The ONstatement can be used |
| to trap integer overflow. |
invalid operation | The |

| such as a NaN. |
