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.

Please view the test code to see what additional features P+ adds to the Prime Programming Language (PPL).

Important

In P+ = is treated as := were in PPL = is treated as ==

Note

The P+ proprietary programming language is susceptible to change, while also maintaining full compatibility with previous versions.
