#14 MAT READ Not Implemented

Paul Edwards — Mon, 08 Sep 2025 08:07:03 -0000

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
retrieving revision 1.4
diff -r1.4 profile.bas
1c1,2
< 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.

MAT READ Not Implemented

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

#2 sigsegv on version 2.30 using Linux

Paul Edwards — Wed, 13 Nov 2024 14:38:09 -0000

The code shown disappeared in a revamp by another developer. If you're still having a problem, I will need a fresh patch.

The latest release (3.30) should have this patch incorporated. Closing now.

Greek characters can't be diplayed.

Giorgos — Fri, 26 Apr 2024 12:33:23 -0000

Hi! :-)

I compiled locally (Linux, Debian based, x64) the latest BWBasic version.

Greek characters, can't be displayed any more.
They are replaced by blank spaces.

Eg. PRINT "ΑΒΓ", returns:

>./bwbasic ABC.BAS

>

Previous versions didn't have this problem.
Bye!!! :-)

Thank you very much.
I can report that your second patch fixed the second bug.
I did your test and everything worked like it should.
Great work!
