- The GRAD User's manual is written for Microsoft C V4.0 (MSC for short)
- users. If you are using Turbo C (TC for short) by Borland, you have to read
- this file. It will describe the difference in using the GRAD library.
-
- Chapter 1
- The speed of GRAD functions for MSC and TC is basically the same because
- most of the low level drawing function is performed by assembly routines. But
- in ellipse drawing, MSC is about 10% faster than TC.
-
- Chapter 2.1 (p.4 near the bottom)
- The command for compiling the program onedot.c should change to
-
- tcc onedot.c gradlib.lib
-
- and include -I and -L option if necessary.
-
- Chapter 2.1 (p.5 bottom)
- The make file should change to:
-
- OPTIMIZE=-O -r -Z
- OPTION=-ms -a -f- -K -c $(OPTIMIZE)
-
- .asm.obj:
- masm /ML $*;
-
- .c.obj:
- cc $(OPTION) $*.c
-
- onedot.obj: onedot.c
-
- onedot.exe: onedot.obj
- tlink /c /d c0s onedot,onedot,nul,gradlib cs
-
- APPENDIX B
- If you need to change the screen memory address (_SCREEN), you have to
- change the address defined in both calcaddr.asm and ftable.c. You cannot change
- the address of the ROM character pattern by changing the value in calcaddr.asm
- when using TC. You need the source listings to do the change when using TC.
