6.9 Hex Dump
HEX DUMP printed data is useful primarily to application program-
mers or customer service representatives as a program debugging or
troubleshooting tool.
To enable HEX DUMP, set the printer control strap A32 IN. Place the
printer on-line.
HEX DUMP causes data received from the host to be printed out in
hexadecimal ASCII form instead of normal printing. A sample is shown
below.
The hexadecimal printout is shown on the left side and the
equivalent plain language printout is shown on the same line at the
right side. Exceptions: ASCII control characters below hexadecimal 20
are printed out as periods. <SP> or hexadecimal 20 causes a blank space
in the equivalent print position. Thus the programmer can examine all
program codes and instructions to determine whether any are correct.
For example, in the first line below, we have:
