==================== Summary ====================

Name: VMMaker.oscog-GAP.2534
Author: GAP
Time: 9 May 2019, 5:12:22.055089 pm
UUID: cd6aae16-6f20-4ddb-9328-64b19b413cb1
Ancestors: VMMaker.oscog-eem.2532

Convert numeric constants to strings for concatenation using #printString.
Required for Pharo compatibility, where the arguments of concatenation are not automatically coerced to strings.
