+.Sh SYNOPSIS
+.Vt extern end ;
+.Vt extern etext ;
+.Vt extern edata ;
+.Sh DESCRIPTION
+The globals
+.Va end , etext
+and
+.Va edata
+are program segment end addresses.
+.Pp
+.Va etext
+is the first address after the end of the text segment.
+.Pp
+.Va edata
+is the first address after the end of the initialized data segment.
+.Pp
+.Va end
+is the first address after the end of the data segment
+.Pq Tn BSS
+when the program is loaded.
+Use the
+.Xr sbrk 2
+.\".Fn sbrk 0
+system call with zero as its argument to find the current end of the
+data segment.

+.Sh HISTORY
+An
+.Nm
+manual page appeared in
+.At v6 .
+.Sh BUGS
+Traditionally, no variable existed that pointed to the start of the
+text segment because the text segment always started at address zero.
+Although it is no longer valid to make this assumption, no
+variable similar to the ones documented above exists to point to the
+start of the text segment.
