.altmacroEnable alternate macro mode, enabling:
LOCAL name [ , … ] ¶One additional directive, LOCAL, is available. It is used to
generate a string replacement for each of the name arguments, and
replace any instances of name in each macro expansion. The
replacement string is unique in the assembly, and different for each
separate macro expansion. LOCAL allows you to write macros that
define symbols, without fear of conflict between separate macro expansions.
String delimiters ¶You can write strings delimited in these other ways besides
"string":
'string'You can delimit strings with single-quote characters.
<string>You can delimit strings with matching angle brackets.
single-character string escape ¶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 ‘!’ (an exclamation mark). For example, you can write ‘<4.3 !> 5.4!!>’ to get the literal text ‘4.3 > 5.4!’.
Expression results as strings ¶You can write ‘%expr’ to evaluate the expression expr and use the result as a string.
No passing arguments to macros based upon keyword assignment. ¶In altmacro mode arguments cannot be passed to macros by keyword assignment. See See altmacro-keyword-arguments for more details
