We provide virtual course about Cobol Programming in english. The first part of this course gives the student a working knowledge of COBOL. They will also gain a solid foundation in the fundamentals of COBOL coding including program structure, design, execution and debugging.
Course description:
The concepts of structured programming are introduced with examples and explanation. Good programming practice is encouraged throughout. The course starts with the basics and furthers learning with hands on assignments until delegates are capable of complex programming logic and design.
In the second part of the course Each delegate will write, execute and debug COBOL programs which stress the advanced features of the language. This will include multi-dimensional and variable length tables, sub-program calls and VSAM file manipulation. Programming standards and style will be addressed throughout.
