This error means?
friends because it gives me this error

Code:
v_n_Valida=`nawk  'BEGIN {
                                                TotDet=0;
                                                NumReg=0;
                                              }
                                              {
                                                if ( substr($ArchPro,1,1) == 0)
                                                {
                                                   NumReg++;
                                                   TotDet= TotDet + int(substr($ArchPro,26,9));

                                               }
                                               } END{
                                                printf ("%d|%d",NumReg,TotDet)
                                              }' $PATH_DAT/$ArchPro`


Code:
nawk: illegal field $(), name "ArchPro"
input record number 1, file /u03/home/apli/fidqa/DATA/MKTMCMRPTO20160121E.DAT

$ArchPro is a reference to a shell variable that cannot be used like that in awk. You need to pass it to nawk:

Code:
nawk  -v ArchPro="$Archpro" ' .... ' "$PATH_DAT/$ArchPro"

The variable ArchPro can then be referenced inside awk (without the $ sign, unless the variable is used to select the field number of the input file)

but that's bad because it gives the error?

The error was there because inside awk the variable ArchPro was empty, so there was a reference to $"" which is a non-existing field.
