A character array can be used as a format in an I/O data transfer statement, with the interpretation that its elements are concatenated in element order to constitute the format. Support in the runtime with an extra optional descriptor argument to six I/O API calls; support in semantics by removing an earlier check for a simply contiguous array presented as a format. Some work needs to be done in lowering to pass a character array descriptor to the I/O runtime API when present Differential Revision: https://reviews.llvm.org/D132167
