Allocation Errors

The following errors can arise during allocation or deallocation of data space.

If the relevant ALLOCATE or DEALLOCATE includes a STAT = specifier, then an occurrence of any of the errors below will cause the STAT variable to become defined with the corresponding error number, instead of the error message being produced.

In the error messages, vartype is

array	a pointer to an array, an allocatable array, or a temporary array
character scalar	a pointer to a character scalar, an automatic character scalar, or a temporary character scalar
pointer	a pointer to a non-character scalar

493	vartype was not created by ALLOCATE.
494	Allocation of nnn bytes failed or Allocation of array with extent nnn failed or Allocation of array with element size nnn failed or Allocation of character scalar with element size nnn failed or Allocation of pointer with element size nnn failed.
