pass one variable as multiple arguments of a function call

[level20peon]

I would like to know if I can do this in one pass (example #1) rather than three passes (example #2):

#include <date.au3>

$datetime='2013-09-05 10:21'
$date=StringRegExpReplace($datetime, '.*?([^-+]*?)-([^-+]*?)-([^ ]*?) .*$', '"$1","$2","$3"')

$Dayofwk=_DateToDayOfWeek($date)

... leads to "Incorrect number of parameters in function call.".

#include <date.au3>

$datetime='2013-09-05 10:21'

$Y=StringRegExpReplace($End_Time, '.*?([^-+]*?)-([^-+]*?)-([^ ]*?) .*$', '$1')
$M=StringRegExpReplace($End_Time, '.*?([^-+]*?)-([^-+]*?)-([^ ]*?) .*$', '$2')
$D=StringRegExpReplace($End_Time, '.*?([^-+]*?)-([^-+]*?)-([^ ]*?) .*$', '$3')

$Dayofwk=_DateToDayOfWeek($Y,$M,$D)

... works as expected.

This StringRegExp function put all digit sequences into an array.

The first three elements of the array will be year, month, and day.

These three elements of the array make up the three parameters of the _DateToDayOfWeek function.

#include <date.au3>
;#include <Array.au3> ; For _ArrayDisplay only

Local $datetime = '2013-09-05 10:21'
Local $aDate = StringRegExp($datetime, '\d+', 3)
;_ArrayDisplay($aDate)

Local $Dayofwk = _DateToDayOfWeek($aDate[0], $aDate[1], $aDate[2])

ConsoleWrite($Dayofwk & @LF) ; Returns 5
ConsoleWrite(_DateDayOfWeek($Dayofwk) & @LF) ; Returns Thursday

Thank you, that works.

Is it generally not possible to take one variable and put the commas - which separate the function arguments - into it and then just call the function with this single variable inside the functions argument brackets?

Think about it, you are providing one parameter. A comma inside that string is just that ... a comma in a string. All you are really passing is a string. If you wanted to get the three required parameters from your string, you could have used StringSplit with the comma as delimiter.
