Talk:FOCAL (programming language)

Gosh, that takes me back! I first used FOCAL on a PDP8-L in 1969 mumble mumble ... Anyway, the TYPE command always preceded numeric output with = on that implementation. Richard Pinch 06:57, 26 August 2006 (UTC)[reply]

It's probably worth mentioning FOCAL's slightly odd subroutine mechanism. DO xx.yy executed line xx.yy and DO xx executed all lines in block xx. The return was simply to finish the line or block, and there was no parameter passing mechanism. Richard Pinch 06:57, 26 August 2006 (UTC)[reply]

Dynamically typed ?

IINM, It's not statically nor dynamically typed. Focal has no data types at all (more precisely, has only one type - real). 89.208.93.254 18:16, 6 March 2007 (UTC)[reply]

Lexicographical Website

Please do not remove the link to the focal.ie article. It is not "extraneous", as both articles have very similar names. Stephen Shaw 21:25, 27 September 2007 (UTC)[reply]

Pruning dead link

I removed the following link. Google turns up no such implementation anywhere, much less at code.google.com. --Vrmlguy (talk) 10:18, 13 September 2008 (UTC)[reply]

Perl implementation of FOCAL-69

Conversion of error address to floating point number

the division by zero error was detected by code at address 4333 so the error message was: ?28.73 @ 01.10

So how does ?28.73 @ 01.10 represent the address 4333? That's not obvious to me, and I think would benefit from a brief explanation. Royhills (talk) 18:51, 11 November 2009 (UTC)[reply]

Yes, that's puzzling me too. I'll try to find out more, and will rewrite/amplify if I can. --Kay Dekker (talk) 20:15, 21 September 2010 (UTC)[reply]
