Created page with "QVAL is used to test if an arguement is true or false in a single line of code. <QVAL <EVAL <LOCAL.A>+1> < <LOCAL.B>? SYSMESSAGE LOCAL.A IS SMALLER:SYSMESSAGE LOCAL.B IS S..."

New page

QVAL is used to test if an arguement is true or false in a single line of code.

<QVAL <EVAL <LOCAL.A>+1> < <LOCAL.B>? SYSMESSAGE LOCAL.A IS SMALLER:SYSMESSAGE LOCAL.B IS SMALLER>

In the above statement is we say that local.a = 3 and local.b = 5

Then local.a+1 = 4

4 being less that 5 means that the argument will return as true and so the first output in the true:false condition will be given

If local.a = 5 and local.b = 5

Then local.a+1 = 6

In these circumstances the argument will return as false and so the condition after : being the false output will be given.

The argument does not have to be greater than or less than, it can also be equal to or even if a specific indicator such as a tag or defname just exists.

Your argument must always be ended with a ?

Must always have 2 possible outputs TRUE:FALSE

And is closed with a >

Be careful if the true:false conditions also require you to use "greater than" It is easy to inadvertently close an argument too soon with a misplaced > after the ? or : in a QVAL argument.

QVAL(test1,test2,res1,res2,res3) in addition to current <QVAL?:> variant. It is useful if dealing with numbers without many IF-s.
Sample <eval qval(<VAR.X>,<VAR.Y>,<VAR.ONE>,<VAR.TWO>,<VAR.THREE>)> will return <VAR.ONE> if <VAR.X> < <VAR.Y>, <VAR.TWO> if they are equal, and <VAR.THREE> if the it is greater. If some of the arguments are omited like qval(1,2,,3) it will default to zero

-In the above statement is we say that local.a = 3 and local.b = 5
+QVAL is a simple form of the IF-ELSE structure. It is used to test if an argument is true or false in a single line of code.
-Then local.a+1 = 4
+For example, this:
-being less that 5 means that the argument will return as true and so the first output in the true:false condition will be given
+ IF (<EVAL <LOCAL.A>+1> < <LOCAL.B>)
-If local.a = 5 and local.b = 5
+...is the same as:
-Then local.a+1 = 6
+ <QVAL <EVAL <LOCAL.A>+1> < <LOCAL.B> ? SYSMESSAGE A+1 is smaller than B:SYSMESSAGE A+1 is greater than or equal to B>
-In these circumstances the argument will return as false and so the condition after : being the false output will be given.
+In the above statement, if we say that local.a=3 and local.b=5, then local.a+1=4
-The argument does not have to be greater than or less than, it can also be equal to or even if a specific indicator such as a tag or defname just exists.
+Since 4 is less that 5, the condition is true, and so the first output (before the : sign) in the true:false condition will be executed
-Your argument must always be ended with a ?
+Since 6 is not less than 5, the condition will return as false and the second output (after the : sign) in the true:false result will be executed.
-Must always have 2 possible outputs TRUE:FALSE
+Your "if condition" is separated from the results by the ? character.  The true and false results are separated by the : character (which is mandatory, even if you dont want anything to happen in one of the cases.)

-QVAL(test1,test2,res1,res2,res3) in addition to current <QVAL?:> variant. It is useful if dealing with numbers without many IF-s.
+...will return <VAR.ONE> if X is less than Y, <VAR.TWO> if they are equal, and <VAR.THREE> if X greater than Y. If some of the arguments are omited like qval(1,2,,3) it will default to zero.
