OACOMP

Parsing Phase

OACOMP begins by parsing the catalog source file specified at run time. When OACOMP parses a catalog source file it:

• upshifts all alphabetic characters. Quoted file specifications and some other quoted strings are not upshifted.
• parses reserved words like TABLE and TYPE.

While parsing, OACOMP displays the string Parsing... on the terminal screen as well as any syntax errors found. For example:

[ -1001] Syntax error in token at line #13
TYPE MASTRE
^

In all syntax error messages, OACOMP displays the line number where the error occurred. In the example above, it is line #13. Below the error message, OACOMP displays the erroneous line with a caret below the first letter of the incorrect token. In the example above, MASTRE is specified incorrectly. The line should have read:

TYPE MASTER

After the parsing phase is successfully completed with no errors, the validation phase is performed.
