Re: %str() use discouraged?

Unless Barbara has some other strange "secret sauce" going on under the covers, any inefficiency would be due to the copying of the string to temporary storage and would therefore depend on its length.

There really is no obvious alternative if the API being called requires a null terminated string. If you concatenate the null to the end of the string manually you're still doing the same copy.

Only potentially faster option I can think of would be to build the string in a varchar that is one byte longer than the biggest string you accept and then using the current length to place the X'00' after the last valid character and then use %Addr(xxxx: *Data).

On anything other than a large string I can't see it making much of a difference.

I have a vague recollection that %str() is horribly inefficient, and its use is discourage. Am I remembering correctly, and is that still applicable to 7.3? If so, is there a preferred alternative?
