Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

::: '''CLOSE''' [''filenumber''[, ...]]
|
|
|
|
|
|
''[[Parameters]]:''
|
|
* ''filenumber'' indicates the file or list of file numbers to close. When not designated all files are closed.
|
|
|
|
|
|
''Usage:''
|
|
* A file MUST be closed when changing to another file mode.
|
|
* CLOSE files when they are no longer needed to save memory.
|
|
* Files cannot be opened in the same [[OPEN]] mode using another number until the first one is closed.
|
|
* Use holding variables for each file number returned by [[FREEFILE]] so that the file reference is known.
|
|
* Will not return an error if a filenumber is already closed or was never opened. It does not verify that a file was closed.
|
|
* [[CLEAR]] will also close all open files.
|
|
* CLOSE can also be used to close an open TCP/IP connection using a handle returned by '''QB64'''.
