That's one of the reasons I tended to use CALL macros for my own stuff
(with bits of ECL embedded in appropriate places as needed) instead of
using vanilla ECL runstreams.  It's a very powerful option.

Here's a little CALL code snippet as an example:

if option('S') then
write '@fjtb';
if parameter(1) = '' then
write 'COPY FLT::FLT*SYSERRSUMMRY.,FLT*SYSERRSUMMRY.,DDP';
else
write 'COPY FLT::FLT*SYSERRSUMMRY(-'||parameter(1)||
').,FLT*SYSERRSUMMRY.,DDP';
endif;
write '@eof';
write '@copy,i flt*syserrsummry.,flt*syserr.'||start_date;
write '@eof';
if parameter(1) = '' then
print 'FLT*SYSERRSUMMRY from FLT will be copied to FLT*SYSERR.'
||start_date;
else
print 'FLT*SYSERRSUMMRY(-'||parameter(1)||'). from FLT will be'
||' copied to FLT*SYSERR.'||start_date;
endif;
endif;
if not option('X') then
print 'Note: Combined report has been written to '||
'TPF$.CONSCHK/REPORT';
query test1 with 'Do you want to view the full report (y/N)?';
if test1 = 'Y' or test1 = 'y' then
if total_lines > 23 then
write '@cshell*cshell.more tpf$.conschk/report';
else
write '@eof';
endif;
endif;
endif;

If you've ever used OS2200 command-line tools like UEDIT, FINDREF, or
CSHELL, this is the macro language they are written in.  FWIW.
