Text Study

I. Pre-reading Exercises

1. Repeat the words in chorus:

A manufacturer, a schedule, utility, executive, assemblers, compilers, interpreters, a linkage, a librarian, errors, responsibility, thoroughly, to verify, debugging.

2. While reading the text you will come across a number of international words. Try to guess what Ukrainian words they remind of you:

A monitor, functions, the service, centers, functions, an object, a catalog, a code, a processor, logic, planning, a test, a programmer, calculation.

3. Pay attention to some grammatical points:

1) These programs are called control programs, language programs and utility programs. 2) Examples of service programs include linkage editors to prepare object programs for execution, a librarian to catalog programs into a library area on magnetic disc, utility programs to transfer data from device to device, and sort­merge programs for sorting data on magnetic tape or disk. 3) As for testing of the computer program, there are two kinds of errors or bugs with which programmers must deal. 4) The first type is the coding error. 5) Such errors are syntax errors that prevent the language processor from successfully translating the source program to object program code. 6) The computer program can be successfully translated, but the program does not produce the desired results. 7) It is the programmer's responsibility to test thoroughly all of the program's functions, in order to verify that the program performs according to specifications.
