ASCII characters and their codes are listed in tables in appendix C.
Record your selection by writing either the 7-bit binary code, or the

NOTE: The module defaults to the colon (:) as the BCD delimiter if you
do not use initialization word four (IW4). However, if you use IW4, you
must enter a BCD delimiter.
Margin justification refers to the manner in which data is displayed by
your ASCII device or stored in the data table (Table 2.H).
Margin justification is particularly evident when the number of data
characters transferred is less than maximum.
Your choice of margin justification depends on the mode of module
operation (Table 2.I).
