Answer / manish dwivedi

By using SCAN OP- Code we can find out the most occurrences
of a character.

Answer / kamlesh

you need to write dow loop ,initialize counter variable=0
and use scan opcode
when first occur of 'd' finds scan returns its position
in string , increment counter=counter+1 then you have to
use substr(yrstring:pos+1:'d')now again same process
is done and if 'd' char found increment counter by 1
this process is continue until complete yrstring is scaned.
finally total number of 'd' is accumulate in COUNTER
variable.

Answer / bharatiya

I was trying it last night and wrote the below code that works for this scenario, please have a look----

DArr1 S 1 DIM(10)
DArr2 S 1 DIM(10)
DCnt S 2 0
Dn1 S 2 0 Inz(1)
Dn2 S 2 0 Inz(1)
DFld1 S 15 Inz('aaabbbbdddddyyy')
C
C Do 15
C EVAL Arr1(n1) = %subst(FLD1:n1:1)

C If Arr1(n1) = 'd'
C Eval Arr2(n2) = Arr1(n1)

C Eval n2 = n2 +1
C Endif
C Eval n1 = n1+1
C Enddo
C Eval cnt = n2 - 1

Answer / kar

Use Scan Opcode, and give the result field as array name
instead of a ordinary field.
After the execution of statement, display array values, and
you can find the all occurrences.

Answer / ssss

fld1 = aaabbbbdddddyyy
res = %check('d':fld1:8) ;
If res > 0;
Cnt = res-8;
Endif;

Answer / vipul dixit

With the help of %Scan built in function or Scan op-code we
can do this.
we should define a data structure and write like this way:-

DDs s
C Eval Ds = %Scan('d':Source:1).
It will fetch the position of the scanned character,and
after that we will count all the positions as DS elements.

Answer / sagar wagh

Dcl-S inputString Char(30) Inz('aaabbbbdddddyyy');
Dcl-S charCount Int(10);
Dcl-S maxCount Int(10) Inz(0);
Dcl-S maxChar Char(1);
Dcl-S i Int(10);
Dcl-S j Int(10);

For i = 1 to %Len(%TrimR(inputString));
charCount = 0;
For j = 1 to %Len(%TrimR(inputString));
If %Subst(inputString: j: 1) = %Subst(inputString: i: 1);
charCount += 1;
EndIf;
EndFor;
If charCount > maxCount;
maxCount = charCount;
maxChar = %Subst(inputString: i: 1);
EndIf;
EndFor;

Dsply ('Character ' + maxChar + ' occurs ' + %Char(maxCount) + ' times');
*InLR = *On;

Answer / manoj

As per my understanding using Scan opcode we can't find out
most occurrences of a character.

Answer / deepak

D:a 15a inz('aaabbbbdddddyyy')
D:b 1a
D:c 15a
D:i 2p 0
D:e 2p 0 inz(1)


C: Eval b=%sst(a:e:1)
C: eval c *cat b
C: If b='d'
C: eval replace(d:x)
C: eval i=i+1
C: eval e=e+1
C: i dsply
C: seton lr

Answer / prasanna

You can find it with opcode scan and in the result field we
should have an array

I have learnt through Net that Debugging a Batch job involves 1. Submit the job with the HOLD (*YES) parameter: SBMJOB HOLD(*YES) or Hold the job queue that before submitting the job by using the HLDJOBQ command. 2. Determine the job name, user, and number of the submitted job by using the WRKSBMJOB command. 3. Type the Start Service Job command on your screen: STRSRVJOB JOB(job name/user/number) 4. Type the Start Debug command on your screen: STRDBG 5. Release the job in the jobq. Type WRKSBMJOB and then put a 6 beside the job to be released and press enter, or, if the job queue was put on hold, release the job queue with the RLSJOBQ command. 6. A display appears when the job is ready to start, saying that you can now begin debugging the job. Press F10 to show the Command Entry display. 7. Now you can start debugging by entering an Add Break Point command: ADDBKP 8.ENDDBG 9.ENDSRVJOB I tried this for RPG/400 Program and up to six steps of the above it's ok,but for me no source is displayed and i typed DSPMODSRC in Command line but still i can't see the sourceif i press F.10 and enter command ADDBKP i don't know how to add break points through it,usually i add break points using F.6 for Interactive job debugs,but since this is batch i don't know sir,Please help me out. I was asked this question in a interview,i know only RPG/400 and i’m asking for debugging of RPG/400 program only sir. or is it only possible to debug BATCH RPG ILE JOB and it is not possible to debug BATCH RPG/400 JOB kindly help me out sir
