<Result> = HDBOpenNoLock(<Logical name of xBase file> , <Abbreviation of xBase file> , <Full name of xBase file>)
<Result>: Boolean - True if the operation was performed,
- False if a problem occurs. HError is used to identify the error.
<Logical name of xBase file>: Character string Logical name given to the xBase file. This name will be used to handle the xBase file by programming. <Abbreviation of xBase file>: Character string Prefix (2 characters) used through programming to identify a file item. For example, the prefix of "Customer" file being CU, the syntax for using the "Name" item of this file is CU.NAME.
Caution: if HDBOpenNoLock opens multiple files, they cannot have the same abbreviation, even if the files have been closed. <Full name of xBase file>: Character string Path and full name of xBase file to open (with the extension). Remarks Caution: HDBOpenNoLock must only be used in the programs that do not modify the file and that use the single-user mode. The opened file is not locked. Therefore, the following functions must not be used after HDBOpenNoLock: - This function is not available when using a database via Remote Access.
- This function is not available when using a stand-alone executable.
