9 Compiler does not allocate space for .SG STRUCTs

A structure declaration incorrectly includes .SG (the system global indirection

symbol). To access the system global area, you can:

Equivalence a structure to a location relative to the base address of the system

global area. (See Section 15, “Privileged Procedures.”)

Declare a system global pointer (using the .SG symbol) and assign a structure

address to it.

Otherwise, declare a global or local structure using the standard or extended

indirection symbol (. or .EXT) and declare a sublocal structure without using any

indirection symbol.

10 Address range violation

This message indicates one of the following conditions:

A declaration specifies addresses beyond the allowable range; for example:

INT i = 'G' + 300;

Declare at most 256 words of directly addressable data relative to 'G', 127 words

relative to 'L', and 31 words relative to 'S'.

A subprocedure parameter or a sublocal variable cannot be accessed because other

items have been pushed onto the data stack. Reorder the parameters or sublocal

data. “Sublocal Storage Limitations” and “Sublocal Parameter Storage

Limitations” in the TAL Programmer’s Guide describes the limitations of sublocal

storage.

The total of primary and secondary global variables exceeds 32K words. Reduce

the number or size of your global variables or move some of them to extended

memory.

The zeroth element of a global direct array is outside G-plus addressing. Declare

the array so that its zeroth element falls within G-plus addressing. If the array is

located at G[0], its lower bound must be a zero or negative value.

The upper bound of the last sublocal array is less than zero. Specify an upper

bound that is equal to or larger than zero.

The size of an indirect array (of structures) exceeds 32K words. Reduce the size of

the array.

The size of a local variable exceeds 128K bytes. Reduce the size of the local

variable.

A procedure that you compile with the SQL directive has more than 122 words of

primary local variables. Declare the excess words as indirect variables.
