Summary

0007257: scripts do not compile

Description

Scripts with a statement like

(status += 32 * !(status & 32));

do not compile. A statement like this comes from the expansion of a preprocessor macro. The macro is called 'SetStatus' in this case. I need it in my scripts --- which run through cpp --- for status handling.

The brackets around the statement are not required in above example. They are required because the macro can be used in an expression like

var1 = var2 * SetStatus(stSOMESTATUS) + var3;

The same goes for other macros that expand to assignments, like replacing elements of a list, for example. The result of an assignment can be used itself as a value, like

var1 = var2 = var3 = 25;

Using macros introduces brackets which are not needed in all instances. However:

+ these brackets don't hurt anything
+ the scripts compile just fine in second life

The syntax check that prevents scripts as described from compiling breaks compatibility with sl for no advantage at all. It should be removed, or changed so that the scripts compile.

It breaks pretty much all my scritps.

Additional Information

I tried this on some sims of Metropolis. I haven't tried other grids; the scripts compile without issues in sl.

I don't know what run mode etc. is used with the Metropolis grid.
