| <dl compact="compact"> |
| <dt><code>LOCAL <var>name</var> [ , … ]</code> |
| <a name="index-LOCAL-name-_005b-_002c-_2026-_005d"></a> |
| </dt> |
| <dd><p>One additional directive, <code>LOCAL</code>, is available. It is used to |
| generate a string replacement for each of the <var>name</var> arguments, and |
| replace any instances of <var>name</var> in each macro expansion. The |
| replacement string is unique in the assembly, and different for each |
| separate macro expansion. <code>LOCAL</code> allows you to write macros that |
| define symbols, without fear of conflict between separate macro expansions. |
| </p> |
| </dd> |
| <dt><code>String delimiters</code> |
| <a name="index-String-delimiters"></a> |
| </dt> |
| <dd><p>You can write strings delimited in these other ways besides |
| <code>"<var>string</var>"</code>: |
| </p> |
| <dl compact="compact"> |
| <dt><code>'<var>string</var>'</code></dt> |
| <dd><p>You can delimit strings with single-quote characters. |
| </p> |
| </dd> |
| <dt><code><<var>string</var>></code></dt> |
| <dd><p>You can delimit strings with matching angle brackets. |
| </p></dd> |
| </dl> |
| |
| </dd> |
| <dt><code>single-character string escape</code> |
| <a name="index-single_002dcharacter-string-escape"></a> |
| </dt> |
| <dd><p>To include any single character literally in a string (even if the |
| character would otherwise have some special meaning), you can prefix the |
| character with ‘<samp>!</samp>’ (an exclamation mark). For example, you can |
| write ‘<samp><4.3 !> 5.4!!></samp>’ to get the literal text ‘<samp>4.3 > 5.4!</samp>’. |
| </p> |
| </dd> |
| <dt><code>Expression results as strings</code> |
| <a name="index-Expression-results-as-strings"></a> |
| </dt> |
| <dd><p>You can write ‘<samp>%<var>expr</var></samp>’ to evaluate the expression <var>expr</var> |
| and use the result as a string. |
