cobol - goback and GO TO paragraph -


is there way can let me cancel effect of "go to" in cobol example:

    perform procedure1 thru e--procedure1     display "perform     procedure2 thru e--procedure2"     perform     procedure2 thru e--procedure2     goback.     procedure1 section.        display "begin============proc procedure1"        perform lecture thru e--lecture        perform endd thru e--endd        display "  endd============proc procedure1"        continue.        exit.    e--procedure1.        exit.       lecture.        display "i label lecture"        go endd        continue.     e--lecture.        exit.      endd.        display "i label endd"        continue.     e--endd.        exit.      procedure2 section.        display "begin============proc procedure2"        display "i label procedure2"        display "  endd============proc procedure2"        continue.     e--procedure2.        exit. 

when code executed, won't see display "perform procedure2 thru e--procedure2", beacause when made go paragraph endd, control permantely transfered paragraph , think there no way can use goback end of proc1 ? am-i wrong ?

@bill

this program trying translate:

goto5pow : proc options(main); dcl file001 file input record env(recsize(15)); dcl ctr1  pic'99' init('0'); dcl carte char(15); call procedure1; put skip list("perform     procedure2 thru e--procedure2"); call procedure2; procedure1: proc;       put skip list("begin============proc procedure1");       on endfile(file001) goto endd;       lecture:       put skip list("i label lecture");       read file(file001) into(carte);       ctr1 = ctr1 + 1;       put skip list("record "||ctr1||"=/" || carte ||"/");       if carte="aaaaaaaaaaaaaaa" goto endd;       endd:          put skip list("i label endd");       put skip list("  endd============proc procedure1"); end procedure1; procedure2 : proc;     put skip list("begin============proc procedure2");     put skip list("i label procedure2");      put skip list("  endd============proc procedure2"); end procedure2; end goto5pow ; 

the output is:

begin============proc procedure1 label lecture record 01=/aaaaaaaaaaaaaaa/ label endd   endd============proc procedure1 perform     procedure2 thru e--procedure2 begin============proc procedure2 label procedure2   endd============proc procedure2 

but cobol, generated output:

begin============proc procedure1 label lecture record 01=/aaaaaaaaaaaaaaa/ label endd begin============proc procedure2 label procedure2   endd============proc procedure2 

as bill said, not use thru. use either procedures or sections; not both. on endfile(file001) sets exception handler end-of file

this program should be:

            03                               pic x value 'n'.                88 file001-eof         value 'y'.                88 file001-has-data    value 'n'.         perform procedure1         display "perform     procedure2 thru e--procedure2"        perform procedure2         goback.         procedure1 section.           display "begin============proc procedure1"           display "i label lecture"           read file001             @ end set file001-eof               true           end-read           if file001-has-data               compute ctr1 = ctr1 + 1;           end-if            display "i label endd"           display "  endd============proc procedure1"            exit.        e--procedure1.           exit.          procedure2 section.           display "begin============proc procedure2"           display "i label procedure2"           display "  endd============proc procedure2"           continue.        e--procedure2.           exit. 

for people more familiar java / c#

on endfile(file001) goto endd; 

setups exception or error handler end-of-file condition. in java like:

try {    ....  } catch (endoffile e) {    goto endd; }
