awk question about BEGIN patttern
 

I have a awk script with the following BEGIN pattern

BEGIN { upper = "PNBRQK"
lower = "pnbrqk"
getline < "lance1.tmp"
cor = substr($0,77,1)
}

I ca use cor inside other patterns when I run the script over lance1.tmp but I woul like to use it when I run the script over other files. How can I do that.

Thanks in advance for any help

Use ARGV and ARGC
 

awk -f your-script.awk name-of-file-to-process

BEGIN { upper = "PNBRQK"
lower = "pnbrqk"
getline < ARGV[1]
cor = substr($0,77,1)
}

ARGV[0] contains "awk"

Use ARGC to see that you have two parameters, one for "awk" and one for your file name.
