In addition to what RudiC has already suggested, since the variable you want to use is the name of the file being processed by your awk script, you could more simply just use:
Code:
nawk '/<name>/{A=1;++i} A{print >> ("cmd" i "_" FILENAME)} /<\/name>/{A=0}' "$entry"

but you may run out of file descriptors (especially with nawk) depending on how many output files you are creating. You could avoid that problem using:
Code:
nawk '/<name>/{A=1;++i} A{print >> (ofn = "cmd" i "_" FILENAME)} /<\/name>/{A=0;close(ofn)} ' "$entry"

You could do it the way you were trying to do it with:
Code:
nawk '/<name>/{A=1;++i} A{print >> (ofn = "cmd"i"_'"$entry"'")} /<\/name>/{A=0;close(ofn)}' "$entry"

but, due to the complicated nesting of quotes, it is harder to read, easier to make mistakes, and harder to debug when it doesn't work.
Or, the way rbatte1 was trying to do it with:
Code:
nawk "/<name>/{A=1;++i} A{print >> (ofn = \"cmd\"i\"_$entry\")} /<\/name>/{A=0;close(ofn)}" "$entry"

but this form gets even harder to read if you have an awk script that uses both shell variables and the contents of awk fields.

It might complain still, but please show us the output, else we're just guessing blind.
