moulinaie Posted October 30, 2011 Share Posted October 30, 2011 Hi all, Does anybody know the GPLLNK equate for Extended Basic??? Guillaume. Quote Link to comment Share on other sites More sharing options...
+RXB Posted October 30, 2011 Share Posted October 30, 2011 Down load the EA Manual and use Page 415 of the Editor Assembler Manual. http://www.retroclouds.de/atariage/Texas_Instruments_Editor_Assembler_Manual.pdf Right here on this site under: http://www.atariage.com/forums/topic/153704-ti-994a-development-resources/ Quote Link to comment Share on other sites More sharing options...
moulinaie Posted October 30, 2011 Author Share Posted October 30, 2011 Down load the EA Manual and use Page 415 of the Editor Assembler Manual. http://www.retroclou...bler_Manual.pdf I have the book, but GPLLNK is not listed !! That's why I'm asking... Guillaume. Quote Link to comment Share on other sites More sharing options...
+RXB Posted October 30, 2011 Share Posted October 30, 2011 GPLLNK page 251. Say when you use Adobe use the Search routine like I do. Click the search icon and type GPLLNK. Quote Link to comment Share on other sites More sharing options...
moulinaie Posted October 31, 2011 Author Share Posted October 31, 2011 Hello, My question was not clear I think... For example, when you use XMLLNK in TI XB environment, yo_u must declare: XMLLNK equ >2018 What is the declaration for GPLLNK ?? It is not in page 251, nor 415-416. Guillaume.

Willsy Posted October 31, 2011 Share Posted October 31, 2011 Rich, The tagged-object loader in the XB cart is a 'reduced functionality' version of the EA tagged object loader. Unfortunately, it doesn't support the REF tag, so it cannot resolve REFd addresses in your assembler source code. It does support the DEF directive (necessary for CALL LINK) which means your only choice is to give the address yourself, which of course means that you need to know it first, in order to specify it as a DEF directive in your source code! Unfortunately Guillame, I do not know the address of GPLLNK in the XB environment, but if you check out the July 1986 edition of the Smart Programmer, you will find a version of GPLLNK listed that you can use. It's not a very large program (70 bytes) and is fully compatible with MiniMem, EA, XB etc. I have posted the magazine below. You need the paper port viewer to view the file, which you can download (free) from here: ftp://ftp.scansoft.c...ort/setupex.exe You may also have the same trouble with XMLLNK. You will want to use XMLLNK if you want to do any floating point math. For XMLLNK you can use the following code, which should work just fine. GPLLNK BSS 32 * workspace for gpllnk DATA LNKGPL * address of code LNKGPL MOV *R11+,@>83E2 * move XML opcode to GPLs R1 MOV @>83F6,R0 * save GPLs R11 LWPI >83E0 * load GPL workspace MOV R1,R2 * copy opcode SRL R1,12 * get table number SLA R1,1 * convert to word offset SLA R2,4 * remove table number from copy SRL R2,11 * get the index into the table A @>0CFA(R1),R2 * get address of pointer MOV *R2,R2 * get address of code from pointer BL *R2 * branch to the code LWPI GPLLNK * restore our workspace MOV R0,@>83F6 * restore GPLs R11 RTWP Hope this helps.

I'm adding the floating point instructions to MLC, so I needed the GPLLNK to get scientific functions. You may also have the same trouble with XMLLNK. You will want to use XMLLNK if you want to do any floating point math. For XMLLNK you can use the following code, which should work just fine. No, XMLLNK works fine directly. The E/A manual gives the new equates to use. I could perform arithmetics with no problem. Thanks a lot Mark, you saved me! Guillaume.

Willsy Posted October 31, 2011 Share Posted October 31, 2011 No problem! There is also an *excellent* article on GPLLNK, specifically relating to XB in the May 1984 edition of The Smart Programmer. See attached. This is probably better than the previous article that I posted. HTH Mark sp8405.zip Quote Link to comment Share on other sites More sharing options...
