RESOURCE_NAME(name16 | string | "string")
specifies a 16-character string that can be used to document and trace the
resource involved in suspend and resume processing. You cannot use register
notation to specify the address of the string.
name16

string A string of characters without intervening blanks; if it is not 16 bytes
long, it is extended with blanks or truncated as required.

in the enclosed string. If you want to document a name (label) in your

Note: RESOURCE_NAME on ADD_SUSPEND supplies a default value which
is used if RESOURCE_NAME is not specified on a SUSPEND call.
RESOURCE_TYPE(name8 | string | "string")
specifies an 8-character string that can be used to document and trace the
resource involved in suspend and resume processing. You cannot use register
notation to specify the address of the string.
