Description

Original issue: https://gitlab.com/lfortran/lfortran/-/issues/164

I have tried to write some legacy code using DATA statement.

REAL :: A
DATA A /8HTESTTEST/
PRINT "(A)", A

I have expected to get the following output:

TESTTEST

But, unfortunately, I got the following output:

Syntax Error:2:0: mismatched input 'DATA' expecting {<EOF>, ';', NEWLINE}
DATA A /8HTESTTEST/

Research direction

No source file, test, or entry point is named. Start by reproducing the shown DATA statement with the Hollerith string and tracing where parsing rejects DATA. Done means the example parses and produces TESTTEST as shown, with coverage for this legacy form.
