Macro

• https://pikchr.org/home/forumpost/83e98ec009
• Once created, a macro cannot be redefined. If you attempt to redefine a macro by providing a second “define” statement with the same macro name, the macro name will be replaced by the previous macro body definition during lexical analysis, likely resulting in a syntax error.

CP: dot invisible;

define flag { 
    line go 1.5 heading $flagAngle \
    then go 0.5 heading $flagAngle + 110 \
    then go 0.5 heading $flagAngle + 250;
    move to CP;
}
margin = 10mm;
$flagAngle = 00;  flag;
$flagAngle = 30;  flag;
$flagAngle = 60;  flag;
