# continue -- continue with the next iteration of a loop

## Synopsis

• Usage:
continue x
• Inputs:
• x
• Consequences:
• the currently executing list-clause of a for-loop or while-loop is finished, and iteration continues with the do-clause or the next iteration of the loop, if any. The value x is added to the list being accumulated. If x is omitted, then no value is added to the list, and the statement may be used in a do-clause.
• Alternatively, as a debugger command, causes execution to be resumed, starting with the current expression.

## Description

 i1 : for i from 1 to 4 list (continue 4; print ho) do print hi hi hi hi hi o1 = {4, 4, 4, 4} o1 : List i2 : for i from 1 to 4 list (continue ; 14) do print hi hi hi hi hi o2 = {} o2 : List i3 : for i from 1 to 4 list 14 do print hi hi hi hi hi o3 = {14, 14, 14, 14} o3 : List i4 : i = 0 ; while i < 10 do ( i = i+1; if i == 5 then continue ; print i ) 1 2 3 4 6 7 8 9 10

Here is an example of the use of continue in the debugger after altering a value so continuation will not cause the error to recur.

 i6 : load "Macaulay2Doc/demo1.m2" i7 : code g o7 = /usr/share/Macaulay2/Macaulay2Doc/demo1.m2:11:7-14:8: --source code: g = y -> ( c := f(y-1); d := f(y-2); c+d) i8 : g 2 /usr/share/Macaulay2/Macaulay2Doc/demo1.m2:8:12:(3):[2]: error: division by zero /usr/share/Macaulay2/Macaulay2Doc/demo1.m2:8:12:(3):[2]: --entering debugger (type help to see debugger commands) /usr/share/Macaulay2/Macaulay2Doc/demo1.m2:8:11-8:13: --source code: b := 1/x; ii9 : code f oo9 = /usr/share/Macaulay2/Macaulay2Doc/demo1.m2:6:8-9:8: --source code: f := x -> ( a := "hi there"; b := 1/x; b+1) ii10 : x oo10 = 0 ii11 : x = 11 oo11 = 11 ii12 : continue 34 o12 = -- 11 o12 : QQ
