Error in awk...
Hi friends...
(Apoloigies for any typos.)
(Don, thanks for your input.)

Consider these two code snippets:-

awkerror1.awk
Code:
#!/usr/bin/awk -f
BEGIN \
{
	SAWTOOTHPLUS64 = " !#$&\'\)*,-/0235689:<>?ABDEGHJKMNPQSTVWYZ\\^_abdeghjkmnpqstvwyz|}~"
	for(LOOP = 1; LOOP <= 13; ++LOOP)
	{
		SAWTOOTHPLUS64 = SAWTOOTHPLUS64 SAWTOOTHPLUS64
	}
	printf("%s", SAWTOOTHPLUS64) > "/tmp/sawtoothplus64.raw"
}

awkerror2.awk
Code:
#!/bin/sh
awk 'BEGIN \
{
	SAWTOOTHPLUS64 = " !#$&"\'\)*,-/0235689:<>?ABDEGHJKMNPQSTVWYZ\\^_abdeghjkmnpqstvwyz|}~"
	for(LOOP = 1; LOOP <= 13; ++LOOP)
	{
		SAWTOOTHPLUS64 = SAWTOOTHPLUS64 SAWTOOTHPLUS64
	}
	printf("%s", SAWTOOTHPLUS64) > "/tmp/sawtoothplus64.raw"
}'

awkerror1.awk works perfectly.

awkerror2.awk gives this error:-
Code:
"""
./awkerror2.awk: line 9: unexpected EOF while looking for matching `"'
./awkerror2.awk: line 11: syntax error: unexpected end of file
"""

./awkerror2.awk: line 9: unexpected EOF while looking for matching `"'
./awkerror2.awk: line 11: syntax error: unexpected end of file
AMIGA:barrywalker~/Desktop/Code/Awk> _

I have found out what is doing it, it is the ' inside the string, even escaping it does not cure the error, only removing it completely does.
I do not understand why a single quote, as part of a string inside double quotes, causes this error nor have I any idea how to cure it.
I have tried to get may amateur haed around it but unable to get it to work.
NOTE; this is more of curiosity as I am now using "#!/usr/bin/awk" for the script, but has "/bin/sh" or "awk" got a bug in parsing?

I await you guys knowledge...

TIA.
