Section 1 – CL Command use

1)      Use of mon-message. A piece of code was given with the MONMSG at procedure level and it was asked where will the control go if an error happened in the processing of a command defined somewhere in the procedure.

2)      Command to write and read a file in CL.

4)      How to retrieve the job date/job name. Available options had RTVJOBA, RTVJOBD etc.

5)      CHGDTAARA command was given with a complex VALUE parameter which contained %SST. Was asked to mark the option, which gives the right value in the Data area.

6)      How can the current library list be changed.

7)      How to debug a program running in batch.

8)      A file with key A is to be accessed randomly on the basis of a field B. Available options  Create a new logical, Opnqry with STRSEQ parameter having B, Sorting the file etc.

4)      How is the format of a date defined at control specification level.

5)      %ELEM was used to define an array in the DIM keyword. Was asked how many records the array will have.

6)      Complex %subst using %scan with addition and subtraction done in the return value of SCAN.

7)      If DIV used with factor 2 zero what will happen. Options available Result indicator will be set on, *PSSR code will be executed, Result factor will have zero etc.

8)      A piece of code was given using DIV opcode where factor 2 was zero and *PSSR subroutine was coded. Was asked to detect what will happen.

9)      A data area DS was given and IN OUT operations performed. Among five different samples of code was asked to find out in which case the Data area will be locked and unlocked.

10)  How to find the Program name and some related information. Options had SDS etc.

11)  An expression using op-codes was to be converted using built in functions - %Dec and %DECH.

12)  What is the correct syntax for Op-code Test(D)

13)  When does a indicator defined in 73-74 position seton while chaining a record.

14)  Except keyword. A file defined in F spec as O type and a DS defined in D spec. How can the file be updated using the DS.

Section 3 – Advanced RPG Programming

1)      Complex Logical expression using Indicators and a variable. Analyzing and determine the result of the variable.

2)      Setting the indicator value by using logical expressions.

*IN50 = (A = B)

what will be the indicator value.

3)      With the same condition as above a complex piece of code was given and the result was to be determined.

4)      A complex logic in words using and either, or, neither to be written in expression.

5)      A complex piece of code with a variable using ITER and LEAVE was given and analyzing that code the value of that variable was to be determined.

6)      How to include a service program in your program.

7)      While creating the program if *OWNER is given to the usrprf parameter what is its significance.

8)      A program ‘A’ compiled with activation grp. *New calls a program ‘B’ compiled in activation grp. QILE. Program B has the following code: -

 Count = count + 1

 Seton     RT

After the program has been invoked 3 times. What will be the value of count?

9)      A Question on the same lines as above but not in different activation group. What will be the value of count?

10)  Where is a prototype defined.

11)  Select the right prototype definition. Extpgm definition was used?

12)  A piece of code for sub procedures was given. What is the length of the value returned?

13)  API for ovrdbf.

Section 4 – Subfiles

1)      There are some 200 records to be loaded. The roll up/down keys should be very fast. Which loading technique to be used.

2)      What does the keyword SFLNXTCHG do.

3)      What does the keyword SFLRCDNBR do.

4)       A piece of code was given using SFLRCDNBR. At what position the cursor will be?

5)      There was a piece of code having different keywords along with there indicators. What will be the indicator positions to initialize the sub file.

6)      If a record has been deleted and you don’t want do display it on the subfile anymore. What is the best possible way to do it?

Section 5 – RPG Performance and Exception/Error Handling

1)      There was some question where some data movement was done and then finally asked what will be the result. Available option Data truncation etc.

Section 6 – RPG Data Handling

1)   A multiple occurrence data structure was defined. How to set the occurrence using the OCCUR opcode.

2)      An EDS was defined using prefix but the fields were not renamed using EXTFLD. What will be the name of the fields used in the program.
