[REBOL] Re: building a dynamic path to elements in block
From: ingo:2b1 at: 1-Nov-2000 0:42
Hi Gary,
a version that works would be:
for count 2 ( div-count + 1 ) 1 [
temp-path: to-path compose [ structure-block 1 (count)]
print temp-path
]
*** output ***
book=O
poem=1
*** /output ***
or
for count 2 ( div-count + 1 ) 1 [
print reduce [to-path compose [ structure-block 1 (count)]]
]
However, why don't you just use 'pick ?
for count 2 ( div-count + 1 ) 1 [
print pick structure-block/1 count
]
This seems the most elegant solution to me ...
regards,
Ingo
