Further Topics in APL

This page covers some additional, more advanced topics not explored fully in the APL tutorial. It is adapted from original material written to accompany MicroAPL's APLX interpreter (not available any more), but the present version has been slightly modified so that examples should work with a number of APLs, including:

• Dyalog APL

• APL2 from IBM

• APL+Win

Where this is not the case this is explicitly stated.
