Hi, PR: 104432 discusses the keyword let, which seems to be nothing more than an alias for expr and works just like it. It appears to have been around since FreeBSD 2.2. At one point, this was documented in the manual pages, originally it was documented in revision 1.9.2.10, RELENG_2_2. That revision was a stable branch at the time and perhaps, when RELENG_3 was branched, the changes were not picked up. I was thinking of removing it, but discussions pushed me to consider placing it under #ifndef _POSIX_SOURCE, kind of like how ed(1) has. Questions/comments? Thanks, -- Tom Rhodes
