Error when importing module

[psacawa]

When running JBOL/examples/script.jq, I encounter the error

jq: error: syntax error, unexpected end (Unix shell quoting issues?) at <top-level>, line 13:
    then ($t*($n-length)) + . end                              
jq: error: Possibly unterminated 'if' statement at <top-level>, line 12:
    if $n > length    
jq: 2 compile errors

which refers to the string module.
