Purogiramu , murairo wekufananidzira unoshandisa chidimbu apo zvishandiso zvinoshandiswa zvinotora maitiro kubva kune rimwe kana mamwe mazita. Muchiitiko chakareruka pane imwe yezvinyorwa zvinoshandiswa, varname , uye rimwe runyorwa, urongwa , iyo inongororwe yemitemo yekupa varname . Mutumbi nharo ndeye Tcl script. Kune chimwe nechimwe chezvinyorwa (zvakarongwa kubvira pakutanga kusvika pakupedzisira), foreach inopa zvinyorwa zvechikamu chacho kuti varname sekuti murairo wekuteerera wakashandiswa kubvisa ichocho, zvino unodana muturikiri weTcl kuti aite muviri .
Zvinyorwa
foreach varname list body
foreach varlist1 list1 ? varlist2 list2 ... ? muviri
Kukurukurirana
Munyaya yakawanda, zvinogona kuva nenhamba yakasiyana-siyana (p., List1 uye list2 ), uye runyoro rwemhando imwe neimwe runogona kuenzaniswa nehuwandu rwezvimwe zvinoshandiswa (eg, varlist1 uye varlist2 ). Pakati pese kuyerwa kwechidimbu, zvigadziriswa zvevarwi vese vanogoverwa zvinoenderana nematauriro anotevera. Maitiro mumutsetse wega wega anoshandiswa nenzira kubva pakutanga kusvika pakupedzisira, uye kukosha kwega kwega kunoshandiswa chaizvo kamwe chete. Nhamba yose yekutora zvinyorwa zvakakura zvakakwana zvokuti ingashandise hutsika dzose kubva pane zvinyorwa zvose. Kana urongwa hunokosha husina zvigadziri zvakakwana kune imwe neimwe yezvinyorwa zvayo zvinoshandiswa mumutambo mumwe nomumwe, maitiro asina chinhu anoshandiswa kune izvo zvisiri izvo.
Kuputsa uye kupfuurira zvinyorwa zvinogona kuiswa mukati memuviri , nechinangwa chakafanana nechekuraira. I f oreach inodzorera tambo isina chinhu.
