CAL: scientific calculator engine
CAL (calculator engine) is a JAL addon to ship as a standalone package the engine which drives TABULA.
Load and run the addon as follows:
load 'math/cal'
For more details, see TABULA and links from that page.
CAL is not intended to be used standalone.
You will only do so if you are writing a new version of TABULA, or investigating / debugging an existing version.
However, to develop t-tables with custom functions, knowledge of CAL is needed besides the TABULA graphic interface.
To make a start at doing this, pick menu: Studio > Labs... then pick item: CAL - the TABULA engine
CAL makes use of the JAL addon: UU, a unit conversion and compute engine. You do not need to load UU yourself, since CAL loads it when it runs.
Both CAL and UU are supported for all J versions and platforms from J version 6.0.2 upwards.
See TABULA for Release Notes for all 3 addons: math/cal, math/tabula, math/uu.
