This program shows both how to define a two-dimensional array and how to access the start and end elements of the array. ==== SOURCE CODE ==== CLS DIM array AS BYTE (6,7) PRINT "array(0,0) = ";array(0,0) PRINT "array(5,0) = ";array(5,0) PRINT "array(0,6) = ";array(0,6) PRINT "array(5,6) = ";array(5,6) array(#5,#6) = 42 PRINT PRINT "array(0,0) = ";array(0,0) PRINT "array(5,0) = ";array(5,0) PRINT "array(0,6) = ";array(0,6) PRINT "array(5,6) = ";array(#5,#6) ==== SOURCE FILE ==== * ''[[https://github.com/spotlessmind1975/ugbasic/tree/main/examples/arrays_examples_04.bas|arrays_examples_04.bas]]'' ==== HOW TO COMPILE AND RUN ==== The instructions here refer to compiling the example from the command line.
