CAN. Command
Case Numeric
Intention
This command can be used to script multiple-choice decisions ("SELECT CASE") using a numerical choice.
Mostly it will be used with SCN. as its for numerical choices.
It has to be used together with:
SCN., or SCS.
and
CAS.,CAE., and ESC..
This Command can be used Single Choice:
CAN.2
and also supports the use of "," and multiple choices like:
CAN.2,3,($$NAT+1),$$PIS,8
See example below.
$$NUM=3
GSB.decide
$$NUM=7
GSB.decide
$$NUM=4
GSB.decide
ENR.
'---------------------
:decide
SCN.$$NUM
CAN.2,3,($$NAT+1),$$PIS,8
DBP.I am here with 2
CAN.(2+1)
DBP.I am here with 3
CAN.4
DBP.I am here with 4
CAE.
DBP. Anything else
ESC.
RET.
It will also work with Floating Point numbers:
$$NUM=6.012
SCN.$$NUM
CAN.6
DBP.I am here with 2
CAN.(5+1)
DBP.I am here with 3
CAN.(6+0.012)
DBP.I am here with 6.012
CAE.
DBP. Anything else
ESC.
ENR.
Syntax
CAN.P1
Parameter Explanation
P1 - Numeric value or variable which shall be compared to the SCS./SCN.-Parameter. Can use Formula in Brakets like: ($$NUM*$$EXP+($$REZ))
which is evaluated at runtime. Actually the result is compared to the Parameter from SCS. or SCN.
CAN. and also supports the use of "," and multiple choices like:
CAN.2,3.534,($$NAT+1),$$PIS,8.3
Supports Floating-Point or Integer Numeric types and Formulas in "(...)".
Speed in Ticks:
This command uses typically around 18(fixed number as Parameter) to 130 Ticks (Variable as Parameter). If you use difficult Formula, even more.

Remarks
please do not write code between the SCS. and the first following CAS./CAN.
While this code will actually be executed, you could get memory-leaks if you jump out of the construct from that place.
Limitations:
There are no relevant nesting limitations.Please always make formulas into () or they may not be calculated.
