Q

What differentiated IBM XL C from other OSs?

A

It supports all the normal C features but also includes z/OS-specific functions and features

26
Q

What are the two scripting languages available in IBM?

A

CLIST and REXX

27
Q

Which is considered the more advanced: CLIST or REXX?

A

REXX is seen as the successor of CLIST

28
Q

CLIST and REXX are run as interpreted or compiled?

A

Interpreted, however REXX does have a compiler

29
Q

A

True

30
Q

What language was adopted by IBM that opened the mainframe up to mainstream Internet processing?

A

Java

31
Q

What is a benefit of Java as a programming language

A

It is written the same way across all systems that run it.

32
Q

As part of IBMs adoption of Java, what aspects of z/OS can be accessed with Java?

A

z/OS data and services
CICS services
Db2 database content
IMS database content

33
Q

What version of z/OS supports Python?

A

> =z/OS 2.3

34
Q

What is a core benefit of using Python?

A

Like Java, the code is written the same no matter where it’s hosted.
Second, it’s a popular language, so there’s plenty of talent available.

35
Q

Through what software can Python developers develop for IBM?

A

IBM Open Enterprise SDK for Python

36
Q

True or False

C and C++ are interpreted languages.

A

False - They are compiled

37
Q

Is COBOL interpreted or compiled?

A

Compiled

38
Q

True or False

C and C++ programs can be compiled by using SDSF.

A

False

C and C++ can be compiled by using the ISPF and JCL interfaces.

39
Q

True or False

The process of compiling a C-source program and then link editing the object deck into a load module is basically the same as it is for COBOL.

A

True

The C/C++ process to create a load module is similar to COBOL.

40
Q

True or False

C and C++ programs can be compiled from within the UNIX Systems Services shell.

A

True

C and C++ programs can be compiled from within the z/OS UNIX System Services shell by using the UNIX shell commands:

c89
cc
c++

41
Q

Which programming language does the code displayed here belong to?

ALLOC FILE(PERSTAX) DA(BVE55.PERSON.TAXDATA) SHR
OPENFILE PERSTAX UPDATE
GETFILE PERSTAX
DO WHILE &SUBSTR(6:8,&PERSTAX)=NO
GETFILE PERSTAX
A

CLIST

Both CLIST and REXX languages consist of text statements that have very similar syntax and structure, but all REXX programs begin with a comment with the word REXX in it.

42
Q

Which two languages are fourth-generation languages?

SAS
FOCUS
Assembly
Java
COBOL
C++

A

FOCUS
SAS

43
Q

What does a precompiler do?

A

They change the structure and language used by subsystems like CICS or Db2 into the source language’s call syntax.

44
Q

What does a compiler do?

A

Accepts a source program to check it for syntax, and produces an object module that contains machine-level code

45
Q

What is it to “bind” the object module?

A

Bind it into an executable module, or a program object.

46
Q

LE

A

Language Environment

47
Q

Langauge Environment

A

A z/OS component that contains standard objects and interfaces for other languages to refer to.

48
Q

How is the security of executables maintained?

A

Through security systems such as RACF

49
Q

What is used to control updates and maintenance of the modules?

A

Software Configuration Manager (SCM)

50
Q

What are stored procedures?

A

Executable code that can be called by other programs via a SQL call statement, where the definition resides in the database

51
Q

When should you sue stored procedures?

A

Use stored procedures for code that is used repeatedly, to reduce network traffic, return result sets to an application, or allow access to data without granting privileges to the applications.

52
Q

What do you use a stored procedure for?

A

mostly used for processes that update or summarize data in the Db2 database, or functions commonly used with the Db2 database.

53
Q

As part of the process required to create an executable module, an object deck has to be run through a process to resolve the addresses where instructions and data will be located. What is this process known as?

A

Bind

54
Q

After you have created an executable module, what controls the processes and users that can access or execute it?

A

RACF

55
Q

What language is the following

REGCHK AMODE 31
               TITLE    'CHECK REGION'
****************************
                SPACE
                DC                C'1'
                DC                C'
                DC                F'60'

A

Assembly
