of the ﬁrst string.

syscmd Executes the HP-UX system command given in the ﬁrst argument. No value is

returned.

sysval Is the return code from the last call to

syscmd.

traceoff Turns off trace globally and for any macros speciﬁed. Macros speciﬁcally traced by

traceon can be untraced only by speciﬁc calls to

traceoff.

traceon With no arguments, turns on tracing for all macros (including built-ins). Otherwise,

turns on tracing for named macros.

translit Transliterates the characters in its ﬁrst argument from the set given by the second

argument to the set given by the third. No abbreviations are permitted.

undefine Removes the deﬁnition of the macro named in its argument.

undivert Causes immediate output of text from diversions named as arguments, or all diver-

sions if no argument. Text may be undiverted into another diversion. Undiverting

discards the diverted text.

(XPG4 only.) It is an error to specify an argument containing any non-numeric character for the built-in-

macros:

decr, divert, incr,

m4exit, substr, undivert, and eval.
