The cache directory contains the cached binary format program codes for the BASIC programs executed. For each BASIC program a new file is generated when the BASIC source code is analyzed and built.
The file name for the cache file is calculated using the file name. This file name includes the full path to the file under Windows NT but is the bare file name as supplied on the command line under UNIX.
This means that if you have two different programs named `hello.bas' in two different directories and you run one after the other from their directory issuing the command line under UNIX
scriba hello.bas
the second execution will erroneously think that the cache file created when the first one was running belong to this program and will execute the binary code.
On the other hand if you execute the program `hello.bas' from two different directories and the supplied paths are different the caching mechanism will not realize that the two execution refer to the same file.
Also note that cache handling does not compare the modification time of the files that basic program includes. If the program itself does not change, but an included file did the caching it will still run the older version.
Caching usually works and in case you experience mysterious problems you can try to avoid caching using the option `-n' or commenting out the configuration line cache. Web servers usually specify full path to the executed code and in that case cache file name conversion is correct. Especially Apache does start CGI programs passing the full path to ScriptBasic as argument and thus caching works well with this web server.
It is recommended to switch the caching totally off during development and switch on at the start of the test phase. On test environment delete the cache frequently whenever you experience mysterious errors that you think you have already corrected.
