Samantha,

Sorry I wasn't more explicit: Yes, each command is a line on its own, followed 
by <Return>. You need to use quotes around your API key, so
  $Env:ALPHAVANTAGE_API_KEY = "[my API key]"

I see that I left off the second quote in the perl command line, it should be 
  perl 'c:\Program Files (x86)\gnucash\bin\gnc-fq-dump currency' USD GBP

The Powershell terminal color-codes errors in red on black, variables and 
special values (e.g. $true, $false) in green, and command names in yellow. 

Regards,
John Ralls
