tcl script not able to read a element from array? [duplicate]

Question

I am taking an array and printing its values using tcl scripts but when I run the script is says can't read "ipname(0)": no such element in array

Here is the code I am using

array set ipname {UART TEST SPI I2C}
set asize 4
for {set i 0} {$i < $asize} {incr i}  {
      puts "$ipname($i) "
}

Your array set command doesn't do what you think. Essentially, it is as if you defined it as follows:

ipname("UART") = "TEST"
ipname("SPI") = "I2C"

What you want is

set ipname(0) "UART"
set ipname(1) "TEST"
set ipname(2) "SPI"
set ipname(3) "I2C"

or

array set ipname {0 UART 1 TEST 2 SPI 3 I2C}
