If the data being the context are isolated then VMS
does have a few relevant features.

Basic (!) example:

$ type data.bas
map (blk) integer accu
$ type sum.bas
program sum

%include "data.bas"
declare integer v

v = -1
while v <> 0
     input v
     accu = accu + v
next
print "sum = ", accu

end program
$ bas sum
$ link sum
$ run sum
1
2
3
0
sum =          6
$
$ run sum
1
2
3
0
sum =          6
$
$ run sum
1
2
3
0
sum =          6
$

[something]

$ type data.bas
map (blk) integer accu
$ type sum.bas
program sum

%include "data.bas"
declare integer v

v = -1
while v <> 0
     input v
     accu = accu + v
next
print "sum = ", accu

end program
$ bas sum
$ link sum + hack/opt ! <---- note the small change
$ run sum
1

3
0
sum =          6
$
$ run sum

0
sum =          12
$
$ run sum

0
sum =          18
