- Information You Need When You Call Technical Support
- ----------------------------------------------------
- When you call Technical Support, please have the following information
- ready:
-
- a. Product name and serial number on your original distribution disk.
- Please have your serial number ready or we will be unable to process
- your call.
-
- b. Product version number.
-
- c. Computer brand, model, and the brands and model numbers of any
- additional hardware.
-
- d. Operating system and version number. (The version number can be
- determined by typing VER at the DOS prompt.)
-
- e. Contents of your AUTOEXEC.BAT file.
-
- f. Contents of your CONFIG.SYS file.
-
-
- 2. CONFIGURING dBASE'S VIRTUAL MEMORY MANAGER (VMM)
- ---------------------------------------------------
- When you run BDC or a dBASE executable file on a system with less than
- 4.5MB extended memory, dBASE's VMM runs automatically and manages your
- system's memory and disk space for the best performance.
-
- You can customize VMM's settings by modifying its configuration file,
- DBASE.VMC, located in the Compiler home directory. If you want to
- customize the environment that your executable file is running in, you
- must rename DBASE.VMC to the name of your executable file. For example,
- if the name of your executable file is TEST.EXE, rename DBASE.VMC to
- TEST.VMC. Then, when you run TEST.EXE, VMM will use the memory settings
- you specified in TEST.VMC.
-
- If you want to limit the amount of memory that dBASE Compiler for DOS
- or your executable file uses without modifying the .VMC file, you can
- use the DOS environmental variable, DOS16M. For example, SET DOS16M=:4M
- limits the Compiler or your executable file to 4MB of memory.
-
- For more information about configuring VMM, read "Optimizing dBASE IV"
- in the dBASE IV 2.0 "Programming in dBASE IV" manual.
-
-
- 3. ERROR MESSAGES
- -----------------
- The dBASE Compiler for DOS error messages are documented in ERRORMSG.TXT,
- a text file that is copied to your Compiler home directory during
- installation.
-
-
- 4. COMPILING AND LINKING IN ONE STEP
- ------------------------------------
- You can specify source files (.PRG, .FRG, .LBG, etc.) as well as
- object files (.DBO, .FRO, .LBO, etc.) in the BDC command line, or
- in a @filelist to compile and link files in one step.
-
- BDC ignores the specified object files during compilation, generates
- object files from the specified source files, then invokes BDL which
- links all the object files.
-
- For example, you can list all the files you want to compile and link
- in a @filelist as follows:
-
- MAIN.PRG
- MYSQL.DBO
- MYBIN.BIN
- MYQBE.QBE
- MYFRG.FRG
- MYFMT.FMO
-
- Then, to compile the source files and link the object files in one
- step, use the BDC command as follows:
-
- BDC @filelist
-
-
- 5. RUNNING AN EXECUTABLE FILE IN MULTIPLE SESSIONS
- --------------------------------------------------
- If you run your executable (.EXE) file in multiple sessions under
- Windows, you must set the file as read-only to avoid share violations.
-
-
- 6. DOCUMENTATION CHANGES
- ------------------------
- - p. 23: The explicit rule example in the "Writing Rules" section
- should be as follows:
-
- myprog.dbo: myprog.prg
- BDC -c myprog.prg
-
