[REBOL] Re: How to compose a string with a specific separator
From: ale870:gm:ail at: 12-Jul-2007 22:36
Hello, I created this small function: composeBlock.
>> composeBlock: func [argDivider [string!] argData [block!] /local newBlock
][newBlock: [] foreach i argData [ app
end newBlock reduce [argDivider i] ] return copy next newBlock ]
>>
>> composeBlock "," [1 2 3 4 5]
== [1 "," 2 "," 3 "," 4 "," 5]
