Glossary V
- variable
- A data object (stored in a memory location) whose value can change
during program execution. A variable can be a named data object, an array
element, an array section, a structure component, or a substring. In FORTRAN 77,
a variable was always scalar and named. Contrast with
constant.
- variable
format expression
- A numeric expression enclosed in angle brackets (<>) that can
be used in a FORMAT statement. If necessary,
it is converted to integer type before use.
- variable-length
record type
- A file format in which records may be of different lengths.
- vector subscript
- A rank-one array of integer values used as a section subscript to select
elements from a parent array. Unlike a subscript triplet, a vector subscript
specifies values (within the declared bounds for the dimension) in an arbitrary
order. Contrast with subscript triplet.
