Limitation: Syntax checking incorrectly identifies errors

The PL/I enhanced editing functionality consists of real-time syntax checking. Some legal PL/I syntax is marked as errors, and some illegal PL/I syntax is not marked as an error.

The following legal PL/I syntax is marked as an error:

• Macros
• Entry constants and entry variables
• Type functions
• Reserved attribute
• Parameter attribute
• limited attribute/option
• Generic attributes
• Factoring of attributes when declaring structures
• isub option with defined attribute
• cdecl, optlink, stdcall attributes of the linkage rule for procedure options
• norescan attribute of activate directive
• tstack attribute of the attach statement
• Implicit variable declarations
• Some legal expressions are marked as errors
• Builtin functions and preprocessor functions

The following illegal PL/I syntax is not marked as an error:

• Condition prefixes for do statements
• Label prefixes for declare, default, when, otherwise, and on statements
• Scaling factors for float or fixed
• Duplicate attributes for declaration statements

The following statements are ignored, so illegal syntax in them is not marked as errors:

• Process statements
• EXEC SQL statements
• EXEC CICS® statements
