How do I determine that the variable contains a ' in the value.
There are many ways of doing so: 
if ($a =~ /'/) {....}
if (index ($a, "'") >= 0) {....}
if (split ($a, "'", -1) >= 2) {....}
if ($a =~ y/'/'/) {....}

how would I change the value in the variable to 
 $a = "A\'\'Bcd"

That's not a clear question. First of all, "A\'\'Bcd" is the same string as "A''Bcd". Do you want backslashes in the resulting value? Second, do you want to change the first quote? The last quote? Quotes between "A" and "B"? All quotes? Only quotes in the second position?
