Bug Fixes</U></STRONG></BIG></P><P><BIG>Since <NOBR>version 1.0</NOBR>, only two serious bugs have been found in<NOBR>ASEM-51</NOBR>:</BIG></P><P><BIG>If DB or DW statements contained at least two subsequent expressions withforward references, followed by at least one further expression or string,the code lengths of these statements were calculated different on <NOBR>pass 1</NOBR>and <NOBR>pass 2</NOBR>. Therefore, jumps to locations behind those statements mighthave led to wrong addresses.</BIG></P><P><BIG>If a symbol name with more than 31 characters was referenced in aninstruction operand, the assembler marked that symbol reference with theerror message </BIG><CODE><NOBR>@@@@@ symbol not defined @@@@@</NOBR></CODE><BIG>,although it was defined correctly above.</BIG></P><P><BIG>Apart of that, some minor deficiencies have been improved or corrected:</BIG></P><P><BIG>The arrows of the error messages in the list file are now pointing moreexactly to the position in the source line, where something is wrong.</BIG></P><P><BIG>ASEM and HEXBIN do no longer crash in exotic I/O error situations(i.e. opening the door of a disk drive while reading from it),and they can output more specific I/O error messages.</BIG></P><P><BIG>It is no longer possible to overwrite the input files by specifyingduplicate file names in the command line.(This does not apply to device names!)</BIG></P><P><BIG>The previous field separator '=' for ASEM and HEXBIN command line optionshad to be changed to ':', because of two reasons:<BR>It is not possible to pass a string, containing an '=' character, to a DOSbatch file as a parameter, and it cannot be assigned to a DOS environmentvariable.<BR>However, the old field separator '=' is still accepted to maintaincompatibility with previous HEXBIN versions.</BIG></P><P><BIG><BR><STRONG><U>2. New Features</U></STRONG></BIG></P><P><BIG>The new assembler version comes up with numerous extensions and improvements:</BIG></P><P><BIG>The /INCLUDES command line option has been introduced to specifydirectories that ASEM has to search for include files.<BR>The /DEFINE command line option has been implemented to define symbolsfrom the command line, for easy assembly of different program variants.<BR>Conditional assembly has been extended with the new IFDEF and IFNDEFmeta instructions.<BR>Primary controls may now be preceded also by general controls.<BR>The new $PHILIPS control allows to switch to the reduced instruction setof the Philips 83C75x family of microcontrollers.<BR>The pseudo instruction NAME has been introduced for compatibility purposes.<BR>The <NOBR>ASEM-51</NOBR> list file has been beautified, and contains more information.New fancy printing facilities have been introduced with the $XREF,$PAGEWIDTH, $DATE, $TITLE and $NOTABS controls.<BR>The $DEBUG, $NODEBUG, $MOD51, $PAGING, $SYMBOLS, and $NOXREF controlshave been implemented for compatibility purposes.<BR>Now all assembler controls may be replaced by their (Intel-) abbreviations.</BIG></P><P><BIG>The error message filter program ASEM2MSG has been introduced, whichallows the integration of <NOBR>ASEM-51</NOBR> into the Borland IDE for DOS.<BR>Files ASEM.PIF and ASEM.ICO have been added to simplify the <NOBR>ASEM-51</NOBR>installation under <NOBR>Windows 3.1</NOBR>.</BIG></P><P><BIG>Device names that are passed to ASEM or HEXBIN as command line parametersmay but need no longer be terminated with a ':' character.</BIG></P><P><BIG><NOBR>HEXBIN 2.2</NOBR> is running about 15% faster than <NOBR>version 2.1</NOBR>.<BR>The length of the binary output file now matches exactly the byte countof the code.<BR>HEXBIN now returns ERRORLEVEL 1 on conversion errors and ERRORLEVEL 2on fatal runtime errors.</BIG></P><P><BIG>With this version, new processor definition files are provided:</BIG></P><TABLE BORDER CELLPADDING=8><TR><TH>File</TH><TH>Manufacturer</TH><TH>Derivatives</TH></TR><TR><TD ALIGN=RIGHT> 89C1051.MCU</TD><TD>Atmel </TD><TD>89C1051, 89C2051</TD></TR><TR><TD ALIGN=RIGHT> 83C451.MCU</TD><TD>Philips</TD><TD>83C451, 80C451, 87C451</TD></TR><TR><TD ALIGN=RIGHT> 83C528.MCU</TD><TD>Philips</TD><TD>83C528, 80C528, 87C528, 83C524, 87C524, 83CE528, 80CE528, 89CE528</TD></TR><TR><TD ALIGN=RIGHT> 83C550.MCU</TD><TD>Philips</TD><TD>83C550, 80C550, 87C550</TD></TR><TR><TD ALIGN=RIGHT> 83C562.MCU</TD><TD>Philips</TD><TD>83C562, 80C562</TD></TR><TR><TD ALIGN=RIGHT> 83C652.MCU</TD><TD>Philips</TD><TD>83C652, 80C652, 87C652, 83C654, 87C654, 83CE654, 80CE654</TD></TR><TR><TD ALIGN=RIGHT> 83C750.MCU</TD><TD>Philips</TD><TD>83C750, 87C750</TD></TR><TR><TD ALIGN=RIGHT> 83C751.MCU</TD><TD>Philips</TD><TD>83C751, 87C751</TD></TR><TR><TD ALIGN=RIGHT> 83C752.MCU</TD><TD>Philips</TD><TD>83C752, 87C752</TD></TR><TR><TD ALIGN=RIGHT> 83C851.MCU</TD><TD>Philips</TD><TD>83C851, 80C851</TD></TR><TR><TD ALIGN=RIGHT> 83C852.MCU</TD><TD>Philips</TD><TD>83C852</TD></TR><TR><TD ALIGN=RIGHT> C501.MCU</TD><TD>SIEMENS</TD><TD>C501-1R, C501-L</TD></TR><TR><TD ALIGN=RIGHT> C502.MCU</TD><TD>SIEMENS</TD><TD>C502-2R, C502-L</TD></TR><TR><TD ALIGN=RIGHT> C503.MCU</TD><TD>SIEMENS</TD><TD>C503-1R, C503-L</TD></TR><TR><TD ALIGN=RIGHT> C511.MCU</TD><TD>SIEMENS</TD><TD>C511, C511A</TD></TR><TR><TD ALIGN=RIGHT> C513.MCU</TD><TD>SIEMENS</TD><TD>C513, C513A, C513A-H</TD></TR><TR><TD ALIGN=RIGHT>COM20051.MCU</TD><TD>SMC </TD><TD>COM20051</TD></TR></TABLE><P><BIG><NOBR>ASEM_51.DOC</NOBR> has been updated accordingly, and extended with analphabetical 8051 instruction table.
