Also Perl, ran on multiple platforms fairly well.

  Tcl and Rexx were around in the same time period as well. And most "personal computers" had a BASIC interpreter at the time (albeit with lots of platform specifics).

    > a program compiled only once to run on more than one kind of computer This is referring to portable object code. Perl, Tcl, and Rexx aren't compiled, but do have source-level portability.

      Perl and TCL do have a VM and bytecode, it's just not used for distribution. The initial releases of Java didn't have a JIT.

      This is referring to pseudo code for a virtual machine — "compiled into p-code" — aka a byte code interpreter.
