If no dbx initialization file is located on startup, dbx assumes ksh mode.

This chapter is organized into the following sections:

Features of ksh-88 not Implemented	page 227
Extensions to ksh-88	page 228
Renamed Commands	page 228

• set -A name for assigning values to array name

• typeset -l -u -L -R -H attributes

• backquote (\Q...\Q) for command substitution (use $(...) instead)

• [ [ expr ] ] compound command for expression evaluation

• @(pattern[|pattern] ...) extended pattern matching

• co-processes (command or pipeline running in the background that communicates with your program)

• $[ p -> flags ] language expression

• typeset -q enables special quoting for user-defined functions
