BRIEF HISTORY

After having issued its Standard ECMA-35 for the extension of the 7-bit coded character set, the coding committee TC 1 of ECMA set up a task group with a view to developing a set of additional control functions. This work was conducted in close co-operation with the coding committee X3L2 of ANSI. Intermediate results were periodically discussed at the meetings of I1SO/TC97/SC2. The first edition of Standard ECMA-48 was issued in September 1976.

In ISO/TC97/SC2 a working party developed an ISO Draft Proposal based on ECMA-48 and on the contributions presented by the representatives of X3L2. Several versions were drafted, submitted to SC2 and up-dated according to the comments received. Finally, at its May 1978 meeting, SC2 adopted the final text which will be processed as a draft international standard and eventually issued as ISO 6429.

This 2nd edition of ECMA-48 is based on the text of DIS 6429 and is technically identical with it. It has been accepted as an ECMA Standard by the General Assembly of ECMA on June 21, 1979.

THIS 2nd EDITION SUPERSEDES THE VERSION DATED SEPTEMBER 1976.
