ILE C/C++ Programmer's Guide
- An ILE C/C++ program can process ICF files as program described files or
as externally described files (the system file QSYS/QICDMF contains a
system-supplied record format).
- The concept of clearing or opening a file using append mode does not apply
to ICF files. If you open an ICF file using append mode (ar+ or ab+),
the file is opened for input and output.
- If you want to write a variable length of data, you must use the keyword
VARLEN in the DDS.
- ICF locale mode can be disabled at the application level by setting the
maximum program devices number to 2 or greater for all ICF files on the
CRTICFF command.
