I'm not 100% on what you're trying to do, an explanation would help.

 

and what are you trying to do with run sub command? You either run the sub or not, subparameters in it is just freaky

I only want to change the string like in the new attachment

 

eat3fish

to

eatmorefish

 

please help, thanks m.

Just use the replace function instead of doing it the way you are trying.

I want to use the substring function and learn to use.

i only used this example. Sorry for making confusion.

I have a string with ZIP Code and Town Name:

 

#string = "USA-24587 Funnytown"

want to separate ZIP Code and Town Name with substr.

result should be

 

#zip = 24587

#town = "Funnytown"

 

Thanks for your service

best regards m.

I needed to do a substring function as well, and here is how I solved it with javascript:

 

I needed to get just the numeric portion of a string like "1.50 x", so I need to remove the last 2 characters in the string.

 

Set
$eval
var ask = '1.15 N';  var output = ask.substring(0,ask.length-2); output;

 

of course I used a {1} variable in the definition of 'ask'.

 

Hope this helps someone!
