ISAM library

Purpose:

It is a library to read and/or modify native structs stored in ISAM files by Java programs in a way that is natural for Java.

Current implementations are:

• VMS index-sequential files (used a lot on VMS)
• BerkeleyDB aka BDB (among other used by GNU Cobol)
• VBISAM (used by GNU Cobol)

Getting started:

See Getting started guide.

System requirements (general):

• Java 1.5 or newer

Additional requirements for VMS index-sequential files:

• VMS C

Additional requirements for BDB files:

• BDB including Java library (jar file) and JNI wrapper (dll/so file) and native library (dll/so file)

Additional requirements for VBISAM files:

• GNU Cobol to provide VBISAM
• gcc compiler
