35 Segment number information lost

If you pass an extended indirect actual parameter to a procedure that expects a

standard address, the compiler converts the address and the segment number is lost.

The resulting address is correct only within the user data segment. Pass an

appropriate address.

36 Expression passed as reference parameter

A calling sequence passes a parameter in the form @identifier to a procedure or

subprocedure that expects an extended pointer as a parameter. If the intent is to pass

the address of the pointer rather than the address stored in the pointer, no error is

involved.

37 Array access changed from indirect to direct

An indirect array is declared inside a subprocedure or is declared as a read-only array.

The compiler changes the indirect array to a direct array because:

The sublocal area has no secondary storage for indirect data.

Code-relative addresses are always direct.

38 S register underflow

The compiler attempted to generate code that decrements the S register below its

initial value in a procedure or subprocedure. If you decide that your source program

is correct, you must insert a DECS directive at that point to recalibrate the compiler’s

internal S register. This is essential in subprocedures, because sublocal variables have

S-relative addresses.

39 This directive cannot be pushed or popped

A PUSH or POP prefix appears on a directive that has no directive stack. Specify the

directive identifier without the prefix.
