Why not write a macro to do this.

Well after a few tries I understand you. The required syntax for this macro
is a little bit backwards and I hope you really mean what you say in your
last paragraph.

Syntax for this macro is:

kill900-910    <- ended with return

Definition is:

kill	%`set \`(IFS=- read x y;echo $x $y)\`;n=$1;while test $n -le $2;do echo -n m${n}\^Mk;n=\`expr $n + 1\`;done`

The ^M should be a return, change it when you do the definition.

This works at om my machine. Sun UNIX 4.2 Release 3.5EXPORT and rn
is the 4.3.2.2

This could cause unwanted things to happen if you are not in the right mode
i.e. article selection level. The indata tests of the script are also very
bad.  kill900-862 should not do anything and kill900-, kill-900, kill900
causes the test to exit with error.
