Reads a file in a fixed-length ASCII format into memory. Each row of the file is delimited with CR or CRLF (carriage return or carriage return + linefeed characters). After the file has been read, the whole file is accessible without further I/O. The file is read into shared memory only once at a client machine, even if it is read by multiple virtual users. Usually, you will use this function in only once in your script for each file you load for example, in a start up transaction that initializes your simulation.
If the file name includes a directory name, the file is opened in the specified directory. Otherwise, Silk Performer searches for the file in the directory where the test script is located, in the data directory, in the results directory and in the project directory.

FileFixedLoad( out hFile : number, in sFileName : string, in sFormatString : string ): boolean;
true if successful
false otherwise
Parameter | Description |
---|---|
hFile | Variable receiving the file handle used to access the file |
sFileName | Specifies the path and file name of the file to read. If you specify a file name without path information, Silk Performer searches for the file in the user data directory specified in the Directories tab of the System Settings - Workbench dialog. |
sFormatString |
Specifies the format of a row in the file. For each column in one row you specify the starting position and the ending position of the column (beginning with 1 as the first position in the row). You need not to specify all columns in a row, and you can specify columns that overlap with other columns. Syntax of the format string Format = Startpos ".." Endpos { ";" Startpos ".." Endpos }. |
