mystring = 'hello world'; sizeof(mystring)
string array
myemptyarray = {}; % create empty string array. myarray = { 'hello', 'world' }; % create array with two strings. myarray(1) % prints 'hello' myarray(3) = 'blah'; %inserts another string into the array. sizeof(myarray) % get number of elements sizeof(myarray(1)) %get length of first string
Note: Arrays are 1-based, not 0-based as they usually are in real programming languages.

for while
switch case
yesno = "yes" switch yesno case {"Yes" "yes" "YES" "y" "Y"} value = 1; case {"No" "no" "NO" "n" "N"} value = 0; case "blah" value = 42; otherwise error ("invalid value"); endswitch
