Non-compilable Program Units
A program unit cannot be compiled unless it is well-formed. A
well-formed program unit has properly matching constructs, such as a NEXT
for every FOR, and its array references are consistent with its array
declarations.
The interpreter checks a program unit's form before executing or saving
it. When a program containing a poorly formed program unit is saved, the
interpreter issues a warning message and marks the program unit as
noncompilable.
If the programmer attempts to compile the program, the compiler issues
the error message
VERIFY is needed on subunit program_unit
and does not generate code for program_unit. The compiler cannot
diagnose the error; the programmer must return to the interpreter and use
the VERIFY command.
