The file format is also used for FID files on the [[Amstrad PCW]]. There are several file formats which use versions of PRL: SPR (System PRL), RSP (Resident System Process). LINK-80 can also produce OVL (overlay) files, which have a PRL header but are not relocatable. [[Graphics System Extension|GSX]] drivers are in PRL format; so are [[Resident System Extension]]s (.RSX). […]}} [https://www.seasip.info/Cpm/amsfid.html#PRL%20file%20format]</ref>

There is a runtime switch which chooses between calling INT 21h (DOS) and INT E0h (CP/M-86). WS.COM is not the same between DOS and CP/M-86, although it's probably not very different either.
