Hello, As I'm often working with boxes of strings I have identified several things that I would like to do with boxed strings but haven't figured how to do yet as I'm still learning J.
[I hope the boxes in the examples don't turn out garbled...] 1. If there is a list of boxed words(strings) how to replace individual items with another string ? For example I have : ] s =: ' ';'this';'is';'a';'sentence' ┌─┬────┬──┬─┬────────┐ │ │ this│ is│a│ sentence│ └─┴────┴──┴─┴────────┘ but would like to use something like: 0 boxitemreplace s; 'is' (to replace the first element which can be a space with 'is) and get this result : ┌──┬────┬──┬─┬────────┐ │is │this │is │a │sentence │ └──┴────┴──┴─┴────────┘ or something like 2 boxitemreplace s;' ' (to replace the third element with a space) ┌──┬────┬──┬─┬────────┐ │ │this │ │a │sentence │ └──┴────┴──┴─┴────────┘ 2. Insert and Remove For example using the same s =: ' ';'this';'is';'a';'sentence': would it be possible to somehow insert a word at a specific index so: 4 inserttobox s;'sample' would yield ┌─┬────┬──┬─┬──────┬────────┐ │ │this │is │a │sample │sentence │ └─┴────┴──┴─┴──────┴────────┘ or remove nth item such as 0 removeitemfrombox s;' ' ┌────┬──┬─┬──────┬────────┐ │this │is │a │sample │sentence │ └────┴──┴─┴──────┴────────┘ 3. And consequently would it be also possible to replace all occurences of one string value within s with another string and remove all occurences of one string from a boxed list such as s ? I more or less know how to do this with regular strings such as s=: 'this is a sentence' but my problem is when dealing directly with boxed strings and when they contain spaces.
