Print Data Byte Map?Pressing YES prints out the present data byte map. Primarily, the data
byte map is a troubleshooting and development tool used in customizing
character sets.
In content, the present data byte map is similar to the active character set
printout. The data byte map not only shows the 256 active character and
control code assignments, as does the active character set, but it also
identifies the source of the character or code.
Part of a data byte map is shown on Page 63 for Data Bytes 96 through
106. Column headings are explained below. (See the "Universal Control
Commands" section for more information concerning data byte maps.) To
stop this three-page printout before completion and to move on to the next
configuration menu item, press EXIT.
Data Byte. The decimal data byte number. Data bytes are numbered 0
through 255.
Action. Indicates whether the data byte is to be interpreted as a printable
character (CHAR) or as a nonprintable control code (CTRL).
Control Code. For a CTRL action, this column contains a standard
abbreviation* for the control code. For example, "FF" would indicate the
form feed control code. If the data byte does not have a control function,
the column contains the abbreviation NUL.
* Appendix D contains a list of standard control code abbreviations.
