If doint the date functions, also look at the IBM *alternative* set by the
INTDATE compiler option.  See:

Hi Tim,
 
Status: I began and had to pause a few weeks ago at home. Basically I wanted
to redo what Ferran Pegueroles and I did with TinyCOBOL. But I'll be glad to
let you go along the lines you outlined.
 
Just one thing related to date functions: the base time in COBOL is 1st
January 1600 AFAICR, while in POSIX (Un*x/GNU/Linux) it is 1rst January
1970. So ideally, we should take into account the COBOL base time, while in
TC we cheated with the POSIX base time: consequence many tests in the 85
testsuite fail.

        Subject: [open-cobol-list] What is the Status of Intrinsic
(internal) cobol FUNCTIONs
        
        
        
        

        Hi, Can you tell me the status of the Intrinsic functions in
open-cobol? I know they were being worked on and we have some code that uses
ORD-MIN, ORD-MAX, CURRENT-DATE, INTEGER-OF-DATE (and a few others). We were
considering writing these ourselves if need be but I don't want to jump the
gun if they're a few weeks or months away and my implementation of
intrinsics would be different than yours..

        Thanks again

         

        Tim Nixon

        Subject: [Maybe Spam] [open-cobol-list] looking for ideas: more on
internals (intrinsics)
        
        
        
        

        We would like to add some of the internal cobol routines for code
we're supporting. For example: ORD-MAX, ORD-MIN, CURRENT-DATE and the like.
My initial concept is to write these in c, and modify the compiler to
understand the FUNCTION statement and map it to the appropriate library
routine, It would be important that the compiler could verify that each was
being supplied with the correct # (and type in the general sense) of
arguments. The implementation of the intrinsics would match the standard for
size, type etc for both arguments and return values. I also would like to
make the implementation robust in the sense that if we began with a few
routines we could easily add others as needed without modifying large
sections of code. Does anyone have any ideas that would be beneficial for
this project?
