binary - Recode the same value pattern for all variables in Stata -


in dataset, have bunch of yes/no type variables. reason, "yes" coded 1 , "no" coded 2 instead of 0. want recode 2 0 based on value label "no".

how can without having check , recode every single one?

there complications:

  1. each of these dummies has value label sharing dummy's name instead of sharing "yesno" value label. therefore, can't loop through variables have "yesno" value label.

  2. there might reserve codes (-1 don’t know, -2 refused, etc.) in these dummies. because of these reserve codes, think best way recode via checking value label because know sure 2 labelled no.

let's suppose looking variables value label attached. can retrieve variables using ds , pass names recode. 

. clear  . set obs 2 obs 0, 2  . forval j = 1/5 {   2. gen y`j' = _n   3. }  . label def yesno 1 yes 2 no  . label val y4 yesno  . label val y5 yesno  . ds, has(vall yesno) y4  y5  . ret li  macros:             r(varlist) : "y4 y5"  . recode `r(varlist)' (2 = 0)

after value label needs adjustment too: 

. label def yesno 0 "no", modify

edit (following helpful remarks @heisenberg)

if using more 1 set of value labels, need apply method repeatedly different value labels or or consider one.

here more general method of looking variables values of 2 have value label "no" attached. warning: should change dataset. make sure save earlier version. 

 ds, has(vall)    foreach v in `r(varlist)' {          local lbl : label (`v') 2          if `"`lbl'"' == "no" {               replace `v' = 0 if `v' == 2               local label : value label `v'               label def `label' 0 "no", modify         }     }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

javascript - IE11 incompatibility with jQuery's 'readonly'? -

the code i'm running has no issues in firefox, or chrome. user typing 1 textbox, tabs next , can continue typing that. when run webpage on ie11, user tabs next textbox , can't type in. textbox has double-clicked before user can insert anything. i've googled , seems ie give problems when using older jquery (i.e. prefers 'prop' 'attr' ). in code below jquery's readonly keyword being used in way ie11 no longer recognise/accept? i assume issue readonly , removeclass('ignore') working expected. //when focus on textbox 1 $("#field1").focus(function() { //remove readonly property textbox 1 $('#field1').prop('readonly', false).removeclass('ignore'); //add readonly property other textboxes $('#field2, #field3, #field4') .prop('readonly', 'readonly').addclass('ignore').val(''); }); i'm using jquery 2.1.3 ...
