I presume you are using bash or similar. bash seems to make a difference between assigning a list of space separated strings to an array variable and assigning the result of a command substitution of same format. Me too, I could not get it to work, other than using the workaround
Code:
var=( $(awk '
             NR==1 { name=$1} 
             NR==3 { dat=$4 "_" $1 "_" $3 "_" $2 "_" $6}
             NR==4 { leng=$1}
             NR==5 { progress=int($1) }
             END{print name, dat, leng, progress};
            ' file ) )
echo ${var[1]}

BTW - the error is originating from you using the reserved word length (function in awk)


After a lot of fiddling around - try this one:
Code:
$ eval var=( $(awk '
              NR==1 { name=$1} 
              NR==3 { dat=$4 " " $1 " " $3 " " $2 " " $6}
              NR==4 { leng=$1}
              NR==5 { progress=int($1) }
              END {print "\""name"\" \"" dat"\" \""leng"\" \""progress"\""};
             ' file ) )
$ echo ${var[1]}
