114
                 Added SET, SETDP, INCLUDE. IF/ELSE/ENDIF
115
                 No macros yet, and no separate linkable modules.
116
 
117
   v0.1.X 99/12/20 added Intel hex option (SLB)
118
 
119
-- H.Seib Additions: --
120
 
121
   v0.2.S 01/10/13 converted to readable format
122
   v0.3   01/10/15 added transfer address processing
123
                   increased max. #symbols and other constants
124
                     (hey, this isn't CP/M anymore :-)
125
                   added a bit of intelligence to command line processing
126
                   loads file(s) into internal storage prior to processing
127
                     (this aids a lot in preventing recursive invocations)
128
                   added LIB,LIBRARY pseudoop (same as INCLUDE)
129
                   added OPT,OPTION pseudoop
130
   v0.4   01/10/22 added -t switch to increase compatibility with the
131
                   TSC FLEX Assembler line, which uses a slightly more
132
                   rigid source file format
133
   v0.5   01/10/23 added SETPG, SETLI, PAG, SPC, NAM(TTL,TITLE), STTL, REP(RPT,REPEAT)
134
   v0.6   01/10/23 added EXITM, IFN, IFC, IFNC, DUP, ENDD
135
   v0.7   01/10/29 added REG, ERR, TEXT
136
   v0.8   01/10/30 converted command line handling to -O switch for options

138
                   RZB pseudoop added
139
   v0.9   01/11/05 clean-ups, increased TSC FLEX Assembler compatibility
140
   v0.10  01/11/15 ASM and VERSION texts predefined
141
   v0.11  01/11/27 increased TSC FLEX Assembler compatibility (labels made case sensitive)
142
   v0.12  01/11/28 added some convenience mnemonics and simulated 6800 instructions to
143
                   increase TSC FLEX Assembler compatibility
144
   v1.02  01/04/11 check for address range overlaps implemented
145
   v1.03  02/09/24 macro parser had an error; corrected
146
   v1.04  02/12/10 error message output adjusted for Visual C++ 6.0 IDE compatibility
147
                   added OPT LFN/NLF for that purpose
148
   v1.05  02/12/23 crude form of backwards ORG added to binary output
149
   v1.06  03/06/10 added OPT LLL/NLL to include/suppress listing of LIB lines
150
   v1.07  03/06/23 outsymtable() only starts with a page feed if current line
151
                   is is NOT the first line on a page
152
   v1.08  03/07/01 SKIP count for the IF(N) and IF(N)C statements added to
153
                   normal statements (i.e., outside macro definitions)
154
   v1.09  05/06/02 some cleanups
155
                   added -r format for FLEX9 RELASMB compatible output
156
                   added ABS, GLOBAL, EXT, DEFINE, ENDDEF, COMMON, ENDCOM
157
                   REL|NOR option added
158
                   GAS|NOG option added (rudimentary)
159

160
   v1.10  05/06/03 made options available as numeric strings
161
                   added local label support
162
                   added SYMLEN
163
                   TXT|NTX option added
164
   v1.11  05/06/06 IFD/IFND directives added
165
                   added special checks for "0,-[-]indexreg" and "0,indexreg+[+]"
166
                   when determining the postbyte for indexed addressing modes
167
   v1.12  05/06/20 OPT CON|NOC correctly implemented
168
   v1.13           skipped for users that might have an uneasy feeling about
169
                   the number "13" >:-)
170
   v1.14  05/08/01 text symbol replacement enhanced; it was a bit TOO general.
171
                   Now, &xxx is only treated as a text variable when xxx REALLY
172
                   is a text symbol; in all other cases, it's not preprocessed.
173
                   Let the assembler engine handle eventual errors.
174
                   Thanks to Peter from Australia for pointing this out!
175
   v1.15  05/08/02 only 1 local label was allowed per address; now, as many as
176
                   possible can be at the same location.
177
                   Thanks to Peter from Australia for pointing this out!
178
   v1.16  05/08/05 SETDP is illegal in relocating mode!
179
                   SETDP without any parameter DISABLES Direct mode entirely.
180
                   Cured an interesting bug... the following sequence:
181
                              ORG 1
182
                              LDA TEST
183
                       SHIT   NOP
184
                              ORG 1
185
                       TEST   RMB 1
186
                   caused a phase error; this was caused by the invalid
187
                   assumption in scanlabel() that forward references have
188
                   a higher memory location than the current address.
189
                   Thanks to Peter from Australia for pointing this out!
190
   v1.17  08/08/05 made tests for above problem more rigorous; now ANY forward
191
                   reference to a label that's not yet defined is treated as
192
                   uncertain.
193
                   Removed a nasty bug that caused the following code to produce
194
                   incorrect values:
195
                            org $8000  (anything >= $8000 will do)
196
                         lbl rmb 8
197
                         SizeBad equ (*-lbl)/2
198
                   OPT NOL changed to OPT NO1 to allow implementing OPT LIS|NOL.
199
                   OPT LIS*|NOL added
200
                   Thanks to Peter from Australia for pointing these out!
201
   v1.18  09/08/05 backward search for local labels now searches for "<= local
202
                   address" instead of "< local address"
203
                   Thanks to Peter from Australia for pointing this out!
204
                   Added INCD / DECD convenience mnemonics
205
                   (realized as ADDD/SUBD 1)
206
   v1.19  10/08/05 Added a bunch of 6800-style mnemonics; if they conflict
207
                   with 6809 mnemonics ("INC A" for example), they are only
208
                   active in TSC mode
209
   v1.20  16/08/05 changed special checks for
210
                     "0,-[-]indexreg" and "0,indexreg+[+]"
211
                   to include all known labels and changed the scope to
212
                     ",[-[-]]indexreg[+[+]]"
213
   v1.21  21/02/06 Bug in "xxx  >0,reg" found by Margus Kliimask
214
   v1.22  03/09/08 Addded BIN(ARY) pseudo-op to include binary files
215
   v1.23  13/02/09 6800 code generation added
216
                   accept multiple input files (first one defines default
217
                     output and listing file names)
218
   v1.24  13/02/09 made compilable with gcc
219
   v1.25  05/03/09 6800 alternate mnemonics work better now
220
   v1.26  14/03/09 assembling DOS format files in Loonix works better now
221
   v1.27  20/01/10 LPA/NLP options added
222
   v1.28  21/04/10 INCD/DECD produced invalid code
