Pascal Literal String

[Gambit]

Hello

I´m trying to use the Delphi grammar found in GOLD web site, with the
last release of GOLD Builder, but I always get a syntax error when the
parser finds a literal string. It is defined as follows:

{String Ch} = {Printable Extended} - {#39} + {HT}

StringLiteral = ( {#39} {String Ch}* {#39} | '#' {digit}+ | '#'
'$' {hex digit}+ | {#39} {#39} )+

Originally it was like this

{String Ch} = {Printable} - [''] + {HT}

StringLiteral = ( '' {String Ch}* '' | '#' {digit}+ | '#' '$' {hex
digit}+ | '''' )+

In both cases I have the same behavior, the parsers stops with an
error saying the token ' (apostrophe) is not expected.

Where I am mistaking?

Thanks in advance.

Hello

I found it! My mistake on understanding the meaning of {Printable
Extended}. I thought that that charset included {Printable} too. So,
the solution is just to define {String Ch} like this:

{String Ch} = {Printable} + {Printable Extended} - {#39} + {HT}

However, the original grammar available in GOLD Parser website still
doens´t work, unless I replace [''] by {#39}.
