one thing about the new tool, and why I thought we might not need two
passes.
Default works this way for a variable (or should)
1.if variable is set with a default value, over-ride the value
2. if variable is not set with a value, set it
3. If variable is set via an option command, do not set value
4. If variable has been used, fatal error
option works this way:
1. If variable is set with a default, set it
2. If variable is not set with a default, set it.
3. if variable is set with an option, fatal error
4. If variable has been used, fatal error
Now, I think if I changed the rules for default above, to:
Default works this way for a variable (or should)
1. if variable is not set with a value, set it
2. if variable has been set with a default, fatal error
2. If variable is set via an option command, do not set value
3. If variable has been used, fatal error
then default and option statements for a single variable can occur in any
order, and the right results will occur. this would eliminate the second
pass.
I think?
