Re: How does one mix ex commands and normal commands such as ma (to set a mark) in a script?

To answer the subject question, one uses :normal in scripts to enter
such commands. Note, however, there is a :mark ex command.

It translates to script directly:

mark a
try
/^$/
catch /E486/
echo 'pattern x not found'
finish
endtry
mark b
try
/^From - /
catch /E486/
echo 'pattern y not found'
finish
endtry
mark c
'a,'bw! file1
'b,'cw! file2

or more simply, without marks:

try
.,/^$/w! file1
catch /E486/
echo 'pattern x not found'
finish
endtry
normal n
try
.,/^If you /w! file2
catch /E486/
echo 'pattern y not found'
endtry

(Note that I've used w! to faciliate rerunning, any existing file1 or
file2 is overwritten.)

> - find a line with pattern x /?x?x?x/
> - ma
> - find a line with pattern y /?y?y?y/
> - mb
> - move all lines with pattern z in a-b to 'a-1

How about for the second task:

try
/?x?x?x/
mark a
.,/?y?y?y/g/pattern z/m 'a-1
catch /E486/
echo v:exception
endtry
