Title: modifier
| Old | New | Line | |
|---|---|---|---|
| 1 | + | **Modifiers** are [[Keyword|keywords]] modifying the standard behavior of a [[Pascal]] language construct, although some modifiers merely serve the purpose of being a *hint* to the compiler. | |
| 2 | + | ||
| 3 | + | ## declaration modifiers | |
| 4 | + | ||
| 5 | + | ### allocation | |
| 6 | + | ||
| 7 | + | - [[Absolute|absolute]] | |
| 8 | + | - [[alias]] | |
| 9 | + | - `cVar` | |
| 10 | + | - `export` | |
| 11 | + | - [[External|external]] | |
| 12 | + | - [[Name|name]] | |
| 13 | + | - `public` | |
| 14 | + | ||
| 15 | + | ### routines | |
| 16 | + | ||
| 17 | + | - [[Forward|forward]] | |
| 18 | + | - `overload` | |
| 19 | + | ||
| 20 | + | ### hint directives | |
| 21 | + | ||
| 22 | + | If `{$modeSwitch hintDirectives+}`, the following [[Hint Directives|hint modifiers]] are available too: | |
| 23 | + | ||
| 24 | + | - `deprecated` | |
| 25 | + | - `experimental` | |
| 26 | + | - `platform` | |
| 27 | + | - `unimplemented` | |
| 28 | + | ||
| 29 | + | These “modifiers” actually have no effect on the generated code, but can be promoted to errors using [[$warn|{$warn}]] (so, for example, in order to ensure `deprecated` functionality is not used in a release version). | |
