Description
The SYS() function returns miscellaneous information depending on <expN>. The arguments and operation of this function are as follows:
Parameter | Description |
---|---|
SYS(0) | Returns complete host system information |
SYS(1) | Returns the current system date as a Julian day number in a character string |
SYS(2) | Returns the number of seconds elapsed since midnight in a character string |
SYS(3) | Returns a unique filename. This will include the full directory path unless SET TMPNAMPATH is OFF (ON by default) |
SYS(5) | Returns 'C:' |
SYS(6) | Returns the current PRINT device as set by the SET PRINTER TO command |
SYS(10,d) | Returns the numeric day number 'd' as a character string |
SYS(11,s) | Returns a date or character string 's' as a character type Julian day number |
SYS(12) | Returns remaining available memory in bytes |
SYS(13) | Returns the status of the printer as "READY" or "OFF-LINE" |
SYS(14,n[,w]) | Returns the index expression for index 'n' in workarea 'w'. If 'w' is omitted then the current workarea is used |
SYS(16) | Returns the name of the currently executing program |
SYS(17) | Returns the CPU type number |
SYS(18) | Returns the name of the GET field being entered |
SYS(21) | Returns the order number of the master index. Note: if the master index is a tag, SYS(21) will always return 1. |
SYS(22) | Returns the master index: the tagname or single index file name. If the master index is a tag, then SYS(22) returns the tag name in upper case. If the master index is a single index, then SYS(22) returns the index file name in lower case, including the file extension. |
SYS(100) | Returns the status of the CONSOLE setting as "ON" or "OFF" |
SYS(101) | Returns the DEVICE setting as "SCREEN" or "PRINT" |
SYS(102) | Returns the PRINT setting as "ON" or "OFF" |
SYS(103) | Returns the TALK setting as "ON" or "OFF" |
SYS(2000,s[,1]) | Returns the name of the first file matching the pattern 's'. If the third parameter is included the next matching file is returned |
SYS(2001,s[,1]) | Returns the current value of the set option 's'. The optional '1' can be used to return the character setting of certain SET COMMANDS, e.g. ALTERNATE |
SYS(2002[,1]) | Turns the cursor OFF (sys(2002)) or ON (sys(2002,1)) |
SYS(2003) | Returns the default directory |
SYS(2004) | Returns the starting directory for the current process |
SYS(2005) | Returns the currently available resource file |
SYS(2007, <expC> [, <expN1> [, <expN2>]]) | Returns the CRC32 checksum for <expC>. |
SYS(2008 [, <expC> [, <expN>]]) | Language compatibility only. |
SYS(2010) | Return the maximum number of open files for the current user |
SYS(2011) | Returns the current lock status, no lock is placed on the record by this command |
SYS(2015) | Returns a unique filename. This will include the full directory path unless SET TMPNAMPATH is OFF (ON by default) |
SYS(2017, <expC> [, <expN1> [, <expN2>]]) | Returns current record checksum (from Lianja v3.4) |
SYS(2019) | Returns name and location of current configuration file |
SYS(2023) | Returns the temporary directory location |
SYS(5000) | Returns amount of currently allocated physical memory for strings |
SYS(5001) | Returns amount of memory allocated for strings |
SYS(5002) | Returns amount of currently allocated memory for indexes |
SYS(5003) | Returns amount of currently allocated memory for symbol table nodes |
SYS(6001) | Returns current DO level as a character string |
Example
? sys(0) system=Win32s on Windows NT nodename=unknown version=6.1 machine=MY-PC
