How to pass Unix shell variables in a awk script

[TDK22]

I've a ksh shell script and i need to merge it with an awk script.
Is it possible to pass variables set in the ksh script in the awk script.
If it's possible, can you say me how??

Thank you in advance for your help

This has been answered many times before in this forum ... have you read the previous threads??

Anyway, there are 2 ways ....

awk '{.......}' var1=$VAR1 var2=$VAR2 filename

or

nawk -v var1=$VAR1 -v var2=$VAR2 '{.........}' filename

The variables are set in the BEGIN action only with the second form (-v) Jean Pierre.

I new to this and can be wrong but I was taught:

variable=this

awk {if('/'"$variable"'/' == $4) print $1, $2}

I just learned to pass variables to my awk scripts.
