1.01 Does not work yet 872 lines of assembler source code 03-19-95 2:32p 1.02 Does not work yet 958 lines of assembler source code 03-19-95 4:07p 1.03 Does not work yet 987 lines of assembler source code 03-20-95 7:45p 1.04 1st version to actually work,but only handles optional format. 1149 lines of assembler source code 03-22-95 6:28a 1.05 Miscellaneous fixes 1169 lines of assembler source code 03-23-95 6:39a 1.06 Took out indented lines for smaller .DXF file. Who cares how pretty it looks? 1169 lines of assembler source code 03-24-95 6:08p 1.07 1st beta release. Added some more error handling & printed some additional info 1243 lines of assembler source code 03-25-95 2:18p 1.08 Added the ability to handle switches & put the /Xclude switch in, but undocumented in help screen 1525 lines of assembler source code 03-27-95 6:53a 1.09 Started working on adding the other 2 DLG formats as well as an automatic test to see what type file it is. 2029 lines of assembler source code 03-30-95 5:56a 1.10 Think I have the standard format working now. 2076 lines of assembler source code 03-30-95 5:56a 1.11 Works with all 3 DLG formats, released to beta testers. 2112 lines of assembler source code 03-30-95 7:37p 1.12 Added /Include=File switch 2187 lines of assembler source code 03-31-95 9:55p 1.13 added ability to add an AutoCAD r12 header to file to solve r13 problem. It now imports into AutoCAD r13 3089 lines of assembler source code 04-02-95 3:52a 1.14 A 1 line addition to turn off a flag. 3090 lines of assembler source code 04-02-95 6:27a 1.15 Miscellaneous fixes. 3136 lines of assembler source code 04-03-95 8:48p 1.16 Miscellaneous fixes. 3144 lines of assembler source code 04-04-95 6:57a 1.17 Fixed a bug where file names without an extention caused it not to put the default layer name in the .DXF file. All you got was a blank line. 3148 lines of assembler source code 04-04-95 6:49p 1.18 Fixed a bug in variable length records created with the unix "dd" command. If the program sees a CR or LF in file, it reads a line at a time instead of a fixed record. This is a bit slower, but does work. 3156 lines of assembler source code 04-05-95 9:11p 1.19 Added displaying of line numbers as they are processed. 3228 lines of assembler source code 04-06-95 5:38p 1.20 Added /N=Lines switch to be able to disable line number counting. Added a check to make sure the .DXF file does not exist before reading .DLG files. Added routine to test for ESCape key, so user could exit prematurely. 3307 lines of assembler source code 04-06-95 7:25p 1.21 Added Comments to the .DXF file & the ability to turn this feature off with the /N=Comments. Added the correct layer count to the default layer header. Fixed a bug in the input file names, where if the files were in a different directory than your default it would not work. Took out the vport stuff from the AutoCAD r12 header file section, since it should not be needed. Started using subroutines for writing the 2 different header types instead of a few conditionals, now there is only 1. 3396 lines of assembler source code 04-08-95 11:15a 1.22 Fixed 2 bugs that had to do with the graphics format. 1st, program was not writing the last digit of minor attribute. 2nd, was not excluding & including properly. Also added line counting for this format. 3416 lines of assembler source code 04-10-95 6:33a 1.23 Added an approximately 4096k read buffer for the 1st pass reading & it increased the speed about 10%. Switched to using the COMPACT memory model so the embedded documentation would not add to my 64k limit on data size. I'm now using only 26k of near data. 3553 lines of assembler source code 04-15-95 5:18p 1.24 Added the read buffer for the 2nd pass on the graphics format. This showed an increase in speed of 25% over no buffer at all. The buffer seems to add to the time on the other 2 formats which seems strange. 3559 lines of assembler source code 04-17-95 7:08p 1.25 Added support for 3d elevation data of hyposograpy data (contours). 3697 lines of assembler source code 06-22-95 7:59p 1.26 Made 3d polylines out of 3d elevation data instead of 2d polylines w/elevations. 3703 lines of assembler source code 01-24-96 9:08p 1.27 Added some more comment lines to allow me to get info about the DLG file that was used to create this DXF which will allow me to use the GCTPC subroutines to convert to several different projection's. Added /2D switch to enable turning off 3d coordinates of contours. 3775 lines of assembler source code 02-22-96 5:41p 1.28 Added checks for valid Line width data & also an additional example line in the usage display. 3808 lines of assembler source code 03-11-96 8:22a 1.29 Added code to insert $EXTMIN, $EXTMAX, $LIMMIN & $LIMMAX into header for optional & standard format only. This occurs only if you use the /H switch. This should cut down on display time bringing it into autocad. Speed decreased by 13%, but the benifits of bringing it in faster into autocad out way that. 4082 lines of assembler source code 03-13-96 6:59p 1.30 Added code to insert $EXTMIN, $EXTMAX, $LIMMIN & $LIMMAX into header for graphics format. 4198 lines of assembler source code 03-13-96 7:30p 1.31 Added the ability to write a release 12 or 10 AutoCAD header. Use the switch /h=10 for release 10 & /h=12 or /h for release 12. Had to rewrite the way I was reading & writing the header info to accomodate this. The number of lines of code got smaller because I made the the AutoCAD header files seperate. 3742 lines of assembler source code 03-18-96 10:43p 1.32 Put in the correct $TDCREATE & $TDUPDATE instead of using the one in the header. This is the Julian date & fraction of a Julian date. Fixed some error handling that was doing a JC instead of a JNE. Most subroutines set carry, but some of the spontaneous routines set non- zero values on error. 3888 lines of assembler source code 03-26-96 6:03p 1.33 Fixed a problem with files that had record delimiters in them. Modified a standard library function to handle reading lines more flexibly. 3930 lines of assembler source code 03-28-96 6:32p
