b c d] and I run a for loop through it, when the loop reaches c, I want to
append [e f g] to the block, and continue running the loop through e f g...)
Try:
Items: [a b c d]
foreach Item Items [
probe Item
if 'c = Item [
append Items [e f g]
]
]
Similar procedure should work for 'for, but I prefer using 'foreach.
