SYSSECELAPSED
Action
Returns the elapsed Seconds to a earlier assigned system-time-stamp.
Syntax
Target = SysSecElapsed(SystemTimeStamp)
Remarks
Target |
A variable (LONG), that is assigned with the elapsed Seconds |
SystemTimeStamp |
A variable (LONG), which holds a Systemtimestamp like the output |
|
of an earlier called SysSec() |
|
|
The Return-Value is in the Range of 0 to 2147483647. The Function is valid from 2000-01-01 to 2068-01-19 at 03:14:07. In the year 2068 a LONG – overflow will occur.
The difference to the pair DayOfSec and SecElapsed is, that SysSec and SysSecElapsed can

be used for event distances larger than 24 hours.

Dim Lsystemtimestamp As Long
Dim Lsystemsecondselapsed As Long
Lsystemtimestamp = Syssec()

'do other stuff
'some time later

SYSDAY
Action
Returns a number, which represents the System Day
Syntax
Target = SysDay()
Target = SysDay(bDayMonthYear)
Target = SysDay(strDate)
Target = SysDay(lSysSec)
Remarks
Target |
A Variable (LONG), that is assigned with the System-Day |
bDayMonthDay A Byte, which holds the Day-value followed by Month(Byte) and Year |
|
|
(Byte) |
strDate |
A String, which holds a Date-String in the format specified in the |
|
CONFIG DATA statement |
lSysSec |
A variable, which holds a System Second (SysSec) |
The Function can be used with 4 different kind of inputs:
1.Without any parameter. The internal Date-values of SOFTCLOCK (_day, _month, _year) are used.
2.With a user defined date array. It must be arranged in same way (Day, Month, Year) as the internal SOFTCLOCK date. The first Byte (Day) is the input by this kind of usage. So the Day of the Year can be calculated of every date.
3.With a Date-String. The date-string must be in the Format specified in the Config Date Statement.

4.With a System Second Number (LONG)
The Return-Value is in the Range of 0 to 36524. 2000-01-01 starts with 0. The Function is valid in the 21th century (from 2000-01-01 to 2099-12-31).

SWAP
Action
Exchange two variables of the same type.
page -685-
© MCS Electronics, 1995-2007
Syntax
SWAP var1, var2
Remarks
var1 |
A variable of type bit, byte, integer, word, long or string. |
var2 |
A variable of the same type as var1. |
|
|
After the swap, var1 will hold the value of var2 and var2 will hold the value of var1.
