I have tried using the code below, but when I run

Code:

awk -f ./addNoise-dat.awk --exapls

I am getting

Code:

MATCH -e: 2 2 2
MATCH --examples: 0 0 -1

Seems it is matching on -e

Code:

  if ( match(ARGV[ARGC-1],"-e") || match(ARGV[ARGC-1],"--examples") ) {
    print "MATCH -e:",match(ARGV[ARGC-1],"-e"), RSTART, RLENGTH
    print "MATCH --examples:",match(ARGV[ARGC-1],"--examples"), RSTART, RLENGTH
    examples()
    exit(1)
  }

Yes, when I use as mentioned, things are fine.

Is there any way I can group /^-e$/ and /^--examples$/ with | inside match?

Code:

if ( match(ARGV[ARGC-1],/^-e$/) || match(ARGV[ARGC-1],/^--examples$/) )

O argv, argv, wherefore art thou argv?

All of my machines (various open source derivatives on x86 and amd64) store argv above the stack (at a higher memory address). I am curious to learn if any systems store argv below the stack (at a lower memory address). I am particularly interested in proprietary Unices, such as Solaris, HP-UX,...
