My reply was based on his diagrammed effort to use one system call to refer
to another system call:

>> if i use (in ruby app:)
>> system(" RSWF_C=1; export RSWF_C" )

>> is this available to all other scripts called from this

The answer is obvious, and I provided it.

If instead his goal can be met by setting ENV variables within Ruby, then
that solves the problem. But before suggesting this, I asked that the OP
first explain what he is trying to do.
