はじめに Enterprise Developer provides two file handlers containing built-in file handling capabilities for all types of file organization.
ファイル編成
This chapter describes the file organizations supported by your COBOL system.
ファイル名
This chapter covers information about file names and their usage, and includes details of the search sequence employed by the run-time system to find dynamically or externally assigned files.
ファイル状態
File status codes are used by this COBOL system to indicate the success, or otherwise, of any file operation carried out by your program.
ファイルの共有
This chapter explains how to prevent more than one user from changing the same data at the same time in a multi-user environment through the use of file and record locks.
ファイル ハンドラーの構成
Certain aspects of the File Handler's behavior can be configured. You can alter these aspects by entering values in the File Handler configuration file, by setting run-time switches, or by setting environment variables.
ファイル ハンドラーおよびソート API
This chapter shows you how to make explicit calls to the File Handler and the Sort Module from your program.
SORT ユーティリティ Enterprise Developer provides MFSORT, a command line sort and merge utility, and MFJSORT, an emulator for DFSORT and SYNCSORT.
Btrieve
Btrieve is the file handling system from Pervasive Software Inc.
データ圧縮およびキー圧縮
Records and keys in files created using the File Handler can be compressed so they take up less physical disk space. You can enable data compression by using the File Handler to call compression routines from your program.
ファイル操作のトレース
Use the tracing file operations, which are provided to help in investigations into problems with file handling.
