[6.17] local variables only lowercase allowed?

RouterOS Scripting
1

Are in local variables only lowercase characters allowed?
I have a strange behaviour within a script.

:local LtgGefunden false;
:set LtgGefunden true;
:if (LtgGefunden = true) do={
	:log info "correct behaviour";
	} else={
	:log info "oops thats wrong"
	};

The behaviour of the script depends on the characters
of the local variable. If there is an uppercase character
in the name of the variable the IF condition fails.

:local LtgGefunden => IF condition fails
:local ltgGefunden => IF condition fails
:local ltggeFunden => IF condition fails
:local ltggefunden => IF condition works

I checked the value of the variable before the IF condition and the value is always equal true.
I use 6.17 on a RB2011 and CCR-1016.
Any idea what´s going wrong here?

FIrst of all, you must write correct syntax, is near all wrong:

:local LtgGefunden value=false;
:set $LtgGefunden value=true;
:if ($LtgGefunden = true) do={
:log info message=“correct behaviour”;
} else={
:log info message=“oops thats wrong”;
};

Hi rextended

it´s the syntax written on the wiki page: http://wiki.mikrotik.com/wiki/Manual:Scripting

Examples:
:global a; :set a true;
:log info “Hello from script”;

But you are right, there is an syntax error in the IF condition I didn´t notice.
The $ was missing. With $ script works.
Thanks.

value= and message= is not necessary $ in set command is not necessary

$ was missing in this line :if ($LtgGefunden = true) do={

On RouterOS 6.7:

[admin@Gateway] > :set x value=3;
expected variable name (line 1 column 6)
[admin@Gateway] > :global x value=3;
[admin@Gateway] > :set x value=3;
[admin@Gateway] > :set $x value=3;
expected variable name (line 1 column 6)

On RouterOS 6.18:

[admin@MATRIX] > :set x value=2;
syntax error (line 1 column 6)
[admin@MATRIX] > :global x value=1;
[admin@MATRIX] > :set x value=2;
[admin@MATRIX] > :put $x;
2
[admin@MATRIX] > :set $x value=3; <<<<< now this instruction do not do error. On 6.7 yes.
[admin@MATRIX] > :put $x;
3
[admin@MATRIX] >

:set has this command line:

:set name= value=

I’m expecting:

:global varname value=test;
:global test value=0;
:set test value=7;

At this point I’m expecting test = 7, and is.

But if I write:

:set $varname value=666;

I’m expecting at this point, set the variable named with the name inside varname to 666:
varname=test
test=666

But… is not.

Is this:
varname=666
test=7

Nested variables are not supported in RouterOS.

v6.18 just has more relaxed syntax. :set x 3 is the same as :set $x 3


What you could do is make an array and then access array elements by keys.
:global a;
:set ($a->“x”) 1;
:set ($a->“y”) 2;

:put ($a->“x”);

Thanks for the detailed reply :wink:
