Editing control structure

'''Control structures''' are constructs used to control the logic of a program based on a given condition. Control structures typically use [[branch]] or [[loop]] statements. Code is typically arranged into [[block]]s within the control structure. === _Conditional Branching_ The following example shows a [[block]] of code being used as a conditional [[branch]]: {{{ awk if (guess == 6) { print "Wow! That was a lucky guess." # we are within an if block here } }}} === _Loops_ The following example shows a [[block]] of code being used within a [[loop]]: {{{ awk for (l = 0; l <= 9; l++) { print l # This runs ten times } }}}
