I wrote program in RPG IV free-form and i met a problem. Im trying to execute sql statment with:
dcl-proc getRecord;
dcl-pi *N int(5) end-pi;
dcl-s rec int(5) inz(0);
exec sql
select max(SCORE) into :rec from SNK_HISC;
return rec;
END-PROC;
It works only once after compilation. Maybe i should reset some indicators or sql flags? At the end of program i use:
*inlr = *on;
return;
Where procedure is called:
exfmt BACK;
exfmt INFO;
inital();
dow run and alive;
write MAINBOARD;
READ(E) AKE_DSP;
run = FKeyListener();
alive = goForward();
ENDDO;
LSCORE = points;
if points > getRecord();
LRECORD = 'NEW RECORD!';
exec sql
insert into AKE_HISC( USID , SCORE) VALUES( :userID , :points);
ENDIF;
exfmt ENDING;
*inlr = *on;
return;
And in this procedure:
dcl-proc inital;
snake(1).x = 5;
snake(2).x = 5;
snake(3).x = 5;
snake(1).y = 5;
snake(2).y = 6;
snake(3).y = 7;
direction.x = 1;
direction.y = 0;
SCORE = points;
RECORD = getRecord();
genSnack();
refresh();
END-PROC;
I run program with this CL program:
PGM
MONMSG MSGID(CPF0000 MCH0000) EXEC(GOTO CMDLBL(END))
OVRDSPF FILE(AKE_DSP) DEV(*REQUESTER) WAITRCD(1)
CALL PGM(AKE_S)
END:
DLTOVR FILE(*ALL)
MONMSG MSGID(CPF0000)
ENDPGM
Problem was not with sql query but with that where it is. I removed procedure getRecord() and make rec global variable and the sql query was placed inside the main cycle thats all.
