Arrays Method 1 If there is a known reasonable upper-bound on the array dimensions, define (by assigning an arbitrary value to it) the highest element of the array. For multi-dimensional arrays, assign the highest element of each possible sub-array. This assignment prevents the arrays from extending. Method 2 Use the TAS function to interlock access to the array. In this case, access to the array is handled exclusively from one or two subroutines that include the TAS to control access to the array. For details, see the TAS program instruction in the eV+ Language Reference Guide . eV+Language User's Guide, v2.x, 18318-000 Rev A Page 46
