idea: %var() function
|
The purpose of the %var() function would be basically to read a variable.
THe reason I'd like to see this happen is so I can give variables complicated names, and go,
#VAR {this variable uses spaces, and @variables in it} {1234}
and then be able to actually read it by going
#SAY %var(this variable uses spaces, and @variables in it).
If there's already a function that does this, I'd really like to hear about it, and I apologize for my frivolty.
If it hasn't, though, I'm sure it could easily be programmed in, just take about two minutes or so. I'd REALLY appreciate it.. |

You can expand variable names to look up a variable based on the contents of another variable. As an example, entering the following from the command line will show "hello world":
#var var1 "hello world"
#var var2 var1
#echo @{@var2}
(Tested with 7.20)
If you want to do it using functions instead of expansion, the following also work as a substitute for the third command:
#echo %eval(@%eval(@var2))
or
#echo %eval(@@var2)
A few examples of syntax are in

Why do you need to be able to include spaces and odd characters?
