Arrays

KSH basic array declaration, access, and manipulation

#!/bin/ksh
# Declare array
set -A fruits apple banana cherry

# Access elements
print "First fruit: ${fruits[0]}"
print "All fruits: ${fruits[@]}"
print "Array length: ${#fruits[@]}"

# Add element
fruits[${#fruits[@]}]="orange"
print "After adding: ${fruits[@]}"

KSH array iteration methods

#!/bin/ksh
set -A colors red green blue yellow

# Method 1: Index-based iteration
integer i=0
while (( i < ${#colors[@]} )); do
    print "Color $i: ${colors[$i]}"
    (( i++ ))
done

# Method 2: Direct iteration
for color in "${colors[@]}"; do
    print "Color: $color"
done
