#IPAS KIT
No, you would not need Phar Lap along with Watcom to create IPAS routines.
If, however, you were to use MetaWare HiC, you would need to have the Phar
Lap kit, since HiC's linker can't provide what's needed. Of course, if you
were intending to do anything that needed some assembly code, then you
would need the phar lap kit anyway, for their assembler.
