Somewhat surprising. In BB4W v6.beta10:
| Platform | Struct.var%(n) | Struct{(n)}.var% | | IDE | 128 cs | 130 cs | | Compiled | 123 cs | 125 cs | | REM!Fast | 96 cs | 98 cs |
But then speed shouldn't really be the deciding factor! And of course much more memory is used by the second option (12 bytes per array element instead of 4).

That's definitely a more useful thing to know. I didn't occur to me that the difference in memory useage would be that much. The program uses thousands rather than ten, so this is worth noting.
Thanks
Matt
p.s. is the REM!Fast a v6 directive? I can't find it in the help.
