edge triggering
A scanner trigger configuration that makes the laser turn on after you pull the
trigger and stay on until you pull it a second time. Simply releasing the trigger
does not turn the laser off. If the laser is left on, the scanner timeout turns the
laser off. Contrast with level triggering.
EMM
Expanded Memory Manager. Software that makes expanded memory available
to EMS-compatible DOS programs.
end device
The device in the data collection system that collects and inputs data.
environment variable
A specification in a program that defines an operating parameter, such as the
command path.
EOF
End of File character. Attached to the last record transmitted in a block of

EOP
End of Program block character. Sent by the host after a block of IRL program
statements to tell the reader that another block of IRL statements is coming.
EOR
End of Record character. Attached to the end of every record transmitted by
the polled device if the EOR character field is enabled.
error message
A message from a device or program advising the user of an error that requires
intervention to solve. For example, if you receive the error message “Error,

you should verify that the command line is correct and then try again.
