#14 MAT READ Not Implemented

[Tom Lake]

MAT READ is not recognized in multiple versions although it's listed in the individual text files. One example is in RSTS-11.

[Paul Edwards]

It appears to be operating as designed.

I don't know if the design is wrong though.

Here are the systems that "MAT READ" is supposed to run on:


bwd_cmd.c:

{
  C_MAT_READ,  /* UniqueID */
  "MAT READ arrayname",  /* Syntax */
  "Matrix read.",  /* Description */
  "MAT READ",  /* Name */
  S70 | D64 | G74 | H14 | HB1 | HB2 | G65 | G67 | D71 | I70 | I73  /* OptionVersionBitmask */
},


I took the last one, I73:

bwb_tbl.c:

{
 "SYSTEM/370",                /* Name */
 I73,                                /* OptionVersionBitmask */
 "I73",                        /* ID */
 "IBM System/370 Mainframe BASIC",        /* Description */



bwbasic.h:

/* OptionVersionValue */
#define B15 (1UL<< 0)                /* Bywater    */
#define S70 (1UL<< 1)                /* CALL/360   */
#define C77 (1UL<< 2)                /* CBASIC-II  */
#define D64 (1UL<< 3)                /* Dartmouth  */
#define E78 (1UL<< 4)                /* ECMA-55    */
#define E86 (1UL<< 5)                /* ECMA-116   */
#define G74 (1UL<< 6)                /* GCOS       */
#define HB1 (1UL<< 7)                /* Handbook1  */
#define HB2 (1UL<< 8)                /* Handbook2  */
#define H80 (1UL<< 9)                /* Heath      */
#define G65 (1UL<<10)                /* Mark-I     */
#define G67 (1UL<<11)                /* Mark-II    */
#define M80 (1UL<<12)                /* MBASIC     */
#define D73 (1UL<<13)                /* PDP-8      */
#define D70 (1UL<<14)                /* PDP-11     */
#define R86 (1UL<<15)                /* RBASIC     */
#define D71 (1UL<<16)                /* RSTS-11    */
#define I70 (1UL<<17)                /* System/360 */
#define I73 (1UL<<18)                /* System/370 */
#define T80 (1UL<<19)                /* TRS-80     */
#define V09 (1UL<<20)                /* Vintage    */
#define T79 (1UL<<21)                /* XBASIC     */
#define H14 (1UL<<22)                /* Haart      */
#define B93 (1UL<<23)                /* Bywater-2  */



And then changed the profile:


D:\devel\bwbasic>cvs diff -l
cvs diff: Diffing .
Index: profile.bas
======================================================
RCS file: \cvsroot/bwbasic/profile.bas,v

diff -r1.4 profile.bas

< option version "bywater"
---
> rem option version "bywater"
> option version "SYSTEM/370"

D:\devel\bwbasic>



And it recognizes the command:

D:\devel\bwbasic>type test.bas
MAT READ x

D:\devel\bwbasic>bwbasic test.bas

ERROR in line 1: Variable Not Declared

D:\devel\bwbasic>



I don't know if that is documented anywhere, but if
you've read the documentation and that isn't specified
and you think it should be documented, please feel free
to submit a documentation patch.


No idea how to use it myself, but the command is
at least recognized.

I have no idea what I was doing wrong before but it's working now. Sorry!
