I would like to modify the following code to make it work:
set i 0
set arg$i {C:/Program File/hell0}
regsub -all -- {/} $arg$i "\x5c" arg$i

I get an error when running this code for the regsub line saying "can't read arg, no such variable". This is true but arg0 does exist and $i is a 0.
Could someone please help with this?
Thanks
 
Hi fhutt,

I would do that using hash like this:

Code:
[COLOR=#804040][b]set[/b][/color] i [COLOR=#ff00ff]0[/color]
[COLOR=#804040][b]set[/b][/color] arg([COLOR=#008080]$i[/color]) {C:/Program File/hell0}
[COLOR=#804040][b]puts[/b][/color] [COLOR=#ff00ff]"arg([/color][COLOR=#008080]$i[/color][COLOR=#ff00ff]) = [/color][COLOR=#008080]$arg[/color][COLOR=#ff00ff]([/color][COLOR=#008080]$i[/color][COLOR=#ff00ff])"[/color]
[COLOR=#804040][b]regsub[/b][/color] -all -- {/} [COLOR=#008080]$arg[/color]([COLOR=#008080]$i[/color]) [COLOR=#ff00ff]"[/color][COLOR=#6a5acd]\x5c[/color][COLOR=#ff00ff]"[/color] arg([COLOR=#008080]$i[/color])
[COLOR=#804040][b]puts[/b][/color] [COLOR=#ff00ff]"arg([/color][COLOR=#008080]$i[/color][COLOR=#ff00ff]) = [/color][COLOR=#008080]$arg[/color][COLOR=#ff00ff]([/color][COLOR=#008080]$i[/color][COLOR=#ff00ff])"[/color]

Output:
Code:
C:\_mikrom\Work>tclsh fhutt02.tcl
arg(0) = C:/Program File/hell0
arg(0) = C:\Program File\hell0
 
Hi microm,
I had this problem before. I couldn't remember how I fixed it, so I did some trial and error. What I came up with is to replace $arg$i with [set arg$i]. Once I got this to work it came back to me that this is what I did before.
However, I prefer your more consistent solution.
Thank you very much.
