#IF then else maybe?
|
#SHOW test is running
#VARIABLE temp "Green"
#IF (@temp=~"Green") {#SHOW "true Green=Green"} {#SHOW "False Green<>Green"}
Can you guess what this will print on your screen after the line "test is running"?
The answer is it prints nothing! We do not go through the true or false part.
This was done on a new char so there were no other alias' to get it messed up.
Anyone any ideas why this fails to display anything?

Yes. Since you have ~", zMUD treats the " as a normal character. It then encounters "), which tells it to treat the ) as part of the string being tested. It never encounters another " to terminate the string and it never encounters another ) to terminate the condition.
Learn to use spaces. 
Any of these will work:
#SHOW test is running
#VARIABLE temp "Green"
#IF (@temp =~ "Green") {#SHOW "1. true Green=Green"} {#SHOW "1. False Green<>Green"}
#IF (@temp=~ "Green") {#SHOW "2. true Green=Green"} {#SHOW "2. False Green<>Green"}
#IF (@temp = "Green") {#SHOW "3. true Green=Green"} {#SHOW "3. False Green<>Green"}
#IF (@temp="Green") {#SHOW "4. true Green=Green"} {#SHOW "4. False Green<>Green"}
#IF (@temp=~"Green"") {#SHOW "5. true Green=Green"} {#SHOW "5. False Green<>Green"} |

Ok thanks for the tip on spaces. Zmud has weird syntax with spaces though, not like most other scripting languages. Sometime you get unxepected results when you have spaces.
So why does @obj not get set, when I use: test Green
#SHOW test is running
#VARIABLE temp "Green"
#IF (@temp =~ "Green") {
#SHOW "1. true Green=Green"
#VARIABLE @obj something
} {#SHOW "1. False Green<>Green"}
#SHOW @obj
If prints "1. true Green=Green" so why not execute the rest of the commands? |

#VARIABLE accepts indirect addressing.
#VAR obj test1
#SHOW test is running
#VARIABLE temp "Green"
#IF (@temp =~ "Green") {
#SHOW "1. true Green=Green"
#VARIABLE @obj something
} {#SHOW "1. False Green<>Green"}
#SHOW {~@temp is @temp, ~@obj is @obj, ~@@obj is @{@obj}} |

In other word you probably want to use:
#VAR obj something |
