### ALP4202: Invalid type expression; cannot convert

Under MASM 5.10 emulation, a constant numeric expression may be used as the left-hand operand of the PTR operator. In the referenced expression, the left-hand operand of the PTR operator did not evaluate to a value suitable for use as the operand size of the right-hand operand. The operand size of the right-hand operator was not converted.
