Accordingly, character sets are very often indicated by their IBM code page number. In ASCII-compatible code pages, the lower 128 characters maintained their standard ASCII values, and different pages (or sets of characters) could be made available in the upper 128 characters.
In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
