Thanks for your reply. Here is an example session run directly (without HOL mode), using a recent development build (commit f65c89f20626b700f7a67ef54b5c80d65a9964d6) with the experimental kernel, and with Poly/ML 5.7.1:

HOL-4 [Kananaskis 11 (expknl, built Wed Apr 11 18:46:29 2018)]
For introductory HOL help, type: help "hol";
To exit type <Control>-D
