Global Variable Transfer Format

Draft MDC Standard

2 Global Variable Transfer Format

The global variable loader shall read and the global variable saver shall produce on the transfer medium the following transfer format:

Header-line1 eol
Header-line–2 eol
Full global variable reference eol
Data contents eol
.
.
.
Full global variable reference eol
Data contents eol
eol
[***GBL END***] eol

Eol is defined to be a logical end-of-line record as mutually defined by the sending and receiving environments.

The full global variable reference shall conform to a global variable name specification as defined by ANSI/MDC X11.1–1994 section 1, subclause 7.1.2.4. When data contains ASCII control characters, decimal (0–31,127), the user shall be responsible for handling the accurate reconstruction of the data string in the host environment. Subscripts in the full global variable reference shall not contain the ASCII control characters decimal 0–31 or 127. Optionally, either two successive blank lines or the string "***GBL END***" denotes the end of the file.

Editor’s note:
The text above contains a reference to ANSI/MDC X11.1–1994. Such a document never existed (there is an X11.1–1995...). Suggest to replace this reference by the appropriate location in this document itself.
