[bug-gawk] gawk 4.0 bug when getline is in BEGIN

[Karl Smith]

BUG : when getline is in the BEGIN block it reads two lines instead of one as the attached program demonstrates

 

gawk –f p2.awk tmpgb2.txt

 

BEGIN{

FS=","

getline

}

{

printf "NR=%s :%s:\n",NR,$0

}

 

--- The output is below and the second line of the input file is not printed

 

NR=1 :IJK,CUKR1,CU1,Pct Diff from Cmp,Grade Bin:

NR=3 :13668,1081.556760,621.300000,0.740796,10:

NR=4 :15158,1090.756667,651.980831,0.672989,10:

NR=5 :15239,1042.806452,402.285714,1.592204,10:

 

--- IF getline is commented out then the output is:
