Language Environment (LE) is a part of OS/390 and allows modern IBM mainframe systems to provide consistent run-time support for COBOL, PL/I, C, Assembler, and Fortran programs. LE also provides a large number of language-independent callable services that application developers may use for various common tasks for example: date calculations, date formats, date conversion, mathematics, scientific calculations, common error handling, and more.

Roadmap to Success

Language Environment (LE) Course Map

 

LE (Language Environment) for OS/390, MVS & VM

Enterprise COBOL Update I: Essentials (2 days)
Experienced COBOL programmers learn to use the major facilities of Enterprise COBOL. Selected facilities of Language Environment (LE) are also introduced.
Enterprise COBOL Update II: Unicode and XML Support (1 day)
Experienced COBOL programmers learn to Enterprise COBOL's Unicode and XML features.
Beyond COBOL II (2 days)
Experienced COBOL programmers will learn to use the major facilities of the COBOL for OS/390 & VM (latest) or COBOL for MVS & VM compiler. Selected facilities of Language Environment (LE) are also introduced.
Converting to COBOL for OS/390 & VM (2 days)
Experienced COBOL programmers learn about features new in COBOL for OS/390 & VM.
COBOL Debugging and Maintenance in the LE Environment (2 days)
Participants learn to use LE Dumps to debug COBOL for OS/390 & VM or COBOL for MVS &VM programs.
Application Development using LE Services (2 days)
Students use VS COBOL II and COBOL/370 facilities for debugging and maintaining programs. The Linkage Editor and Program Binder are discussed extensively.
Application Development using LE Services and Beyond COBOL II (4 Days)
Participants will practice with the wide range of services available from LE for OS/390 & VM to application programs and learn of new COBOL features.
Inter-Language Communication in OS/390 (3 days)
>Experienced programmers will learn the most productive ways to combine functions and modules written in different languages. Specifics on how each language builds and accesses arguments/parameters will help the student build applications that are smaller, faster, and more robust.
C on z/OS (3 days)
Students familiar with the C language will learn how to use C under IBM's z/OS (MVS, OS/390) operating system. Topics include: interaction with JCL, sequential files, PDS members, VSAM, CICS, IMS, and DB2.
