#22 Parsing: Missing data types

[Simon Sobisch]

At least binary-long should be fixed in [r118], didn't checked the fix yet

• 2002 standard: use of "constant"
• 2002 standard: use of new data types that don't need (aren't allowed to have) a picture clause (full list of usage: binary-char, binary-short, binary-long, binary-double, float-short, float-long, float-extended, index, object reference, pointer, program-
  pointer)
• as a common extension: data types that don't need (aren't allowed to have) a picture clause: BINARY-C-LONG, SIGNED-INT, UNSIGNED-INT, SIGNED-LONG, UNSIGNED-LONG, SIGNED-SHORT, UNSIGNED-SHORT
• COMP-X data type (a common extension [simply parse like other COMP types - needs picture clause])

[Simon Sobisch]

Rechecked with [r140] - everything above is accepted, despite of "constant" (doesn't work the way it's implemented in the grammar). Not sure if everything is checked in the test suite (especially the part "usages that aren't allowed to have a picture clause").

[KrisDS]

Indeed, the "not allowed" checks are still missing.

[KrisDS]

Given the nature and goals of Koopa I'm not going to add "not allowed" checks. I really want to accept as much as possible syntactically, even if certain combinations may not be allowed semantically. I would rather see such things added as a semantic pass on the syntax tree.

[Simon Sobisch]

You've added CONSTANT AS in the meanwhile, did you?

Likely something for a new ticket is the RETRY phrase and DYNAMIC LENGTH

[KrisDS]

Yes, CONSTANT AS is covered by the constantEntry_level01 rule.

RETRY and DYNAMIC LENGTH are indeed missing. Feel free to create tickets for those. :-)
