How do you pass a value to a macro using vbscript?

[kinook]

The macro is updated immediately; the sample demonstrates retrieving and updating in the same step. You may have a temporary macro with the same name defined, which overrides the project macro value.

Otherwise, please ZIP and send or post:
1) The info from Help | About | Install Info
2) The .bld file demonstrating the problem
3) A build log file

Thanks.
