The version is usually in the compiler listing, on each page. On recent
VMS versions with "pipe" one can get to the version with something like

$ pipe fort/old/list=sys$output nl:/noobj | (read sys$pipe x ;
x=f$edit(x,"compress,trim") ; x=x-f$element(0," ",x)-f$element(1,"
",x)-"Page 1" ; write sys$output f$edit(x,"trim"))
Compaq Fortran 77 V7.2-180
$

Or, if you like GNV more than UNIX :-)

bash-4.3$ dcl 'fort/old/list=sys$output nl:/noobj' | head -n1 | awk
'{for (i=3; i<NF-1; i++) printf "%s ", $i; printf "\n"}'
Compaq Fortran 77 V7.2-180
bash-4.3$

Shouldn't be a big deal to write a generic script to do this for all the
compilers, available on your system.
