PCL for Everyone
Entering Equations
?
Use of PCL when creating spatial fields:
?X + ?X**2 – sinr(?X)
The PCL interpreter interprets anything immediately following a ? symbol as a field variable as opposed to a PCL function, such as, sinr().

Entering Data
?
Use of PCL when entering geometric coordinates:
[ `5./16.` 0 0 ]
The PCL interpreter “evaluates” expressions enclosed in back tics, “`”.
Other examples:
[ `radius/length` 0 0 ] < `cosr(theta)` 1 1 >
[ `MyFunction(radius)` 0 1 ]

Session Files
?
Session and journal files are comprised entirely of PCL
commands. Model changes (dimensions, mesh density, etc.) can be made quickly by editing and then replaying the session or journal files.
