The error is with the to-integer and not load, so load seems to be
loading your bad path ok.
What are the paths to? If to files and pass is a string, then load
will quite happily load the string. Changing [load pass] to [load
to-file pass] will generate an error if it's not a file.
load, (roughly speaking), converts a file or string to REBOL format.
Hence the following loads quite happily and generates a block...
>> test: load "aa %bb cc"
== [aa %bb cc
]
>> type? test/1
== word!
>> type? test/2
== file!
Hope this helps, but if it's not a file you're trying to load then it
probably won't...
