Any compile time error
undefined argument
undefined preprocessor
CAUSE:
The compiler has problems to handle an undefined argument/preprocessor and leaves a curly bracket ('}') if it is not followed by a space or a carriage return. Development is aware of it.
Example:
/*test.p*/
DEFINE VARIABLE c AS CHARACTER NO-UNDO.
c = &IF "{&DataType}":U = "LOGICAL" &THEN NO &ELSE {&DataType}('') &ENDIF.
If you do a COMPILE test.p PREPROCESS test.txt, and open test.txt, you will see it results in:
c = }(??).
FIX:
Either add a space after the braces (works fine with this example):
c = &IF "{&DataType}":U = "LOGICAL" &THEN NO &ELSE {&DataType} ('') &ENDIF.Or use the DEFINED() preprocessor function (when an extra space is not an option):
c = &IF "{&DataType}":U = "LOGICAL" &THEN NO &ELSE &IF DEFINED(DataType) = 0 &THEN ('') &ELSE {&DataType}('') &ENDIF &ENDIF.
