found it (sort of)
Despite the absence of any reply (not sure if this question was in the wrong place or just didn't interest anybody!) i have found an answer which i will post as I know from past experience that nothing is more frustrating than trawling the Net for something find it and then found its not been followed up.
I managed to achieve my goal by having the external shell script write out the value to a file in /tmp, the macro then read in the file to the current file , deleted the line and assigned it to buffer 'a' and then using the @ notation to pass to the : (go to line) command.
map ^[[O :!goto_func %^M :r /tmp/goto.mac^M "add:@a^M : !rm -f /tmp/goto.mac^M
still a bit cludgy as edits the existing file, (im thinking is there a way of reading directly into the buffer?) if anyone has a more elegant solution then please post it here.

shell
shell(1F) FMLI Commands shell(1F)
NAME
shell - run a command using shell
SYNOPSIS
shell command [command] ...
DESCRIPTION
The shell function concatenate its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise
/usr/bin/sh).
EXAMPLES
Example 1 A sample output of shell command.
Since the Form and Menu Language does not directly support background processing, the shell function can be used instead.
`shell "build prog > /dev/null &"`
If you want the user to continue to be able to interact with the application while the background job is running, the output of an exe-
cutable run by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to
save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing.
shell can also be used to execute a command that has the same name as an FMLI built-in function.
NOTES
The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local environments
will not be expanded by the shell because "local" means "local to the current process."
