P+ is a proprietary programming language designed to mitigate the challenges associated with code maintenance and comprehensibility in the HP Programming Language (PPL). P+ serves as an intermediary language that addresses these issues by introducing support for substitutions and facilitating code organization. The final output is a PPL program file with a minimal footprint, optimized to conserve the limited storage space available on the HP Prime.
P+ is essentially the PPL language with additional features, such as substitution capabilities, and requires all keywords to be in lowercase.
Note
p+, pplmin, pplref, and grob are no longer installed in /usr/local/bin. To uninstall them manually, just drag these four files to the trash.
The folder in your home folder ~/primeplus-toolchain
that is created during the old installing of PrimeSDK can be removed.
