Macros - entering across multiple lines

GAMS
1

hi

is it possible to enter a macro over multiple lines?

eg something like:

$macro myMacro
if (a = 1) then
do something;
else
do something else;
endif;


As I have not seen a terminating macro command I wasnt sure its
possible, but if there’s a way I would love to know.

The driver is that some of my macros are fairly big and ugly when
written on 1 line.

Thanks
Andy C

Andy,

23.1 and later allow macro continuation characters. This is described
in the release notes of 23.1 and is featured in the testlib model
macro02: http://www.gams.com/testlib/libhtml/macro02.htm

While you can do a lot with macros, the intent was to have a compact
representation of (recursively defined) expressions. Your example uses
it for multiple statements. Be aware of macro expansion and compile
time statements.
