Is ARM Keil IDE case-sensitive for all ARM assembly instructions? Is it indentation-sensitive?

Personal experience, Case insensitive, Indentation sensitive.

The latter especially when determining if it is a label vs opcode. Comment and label forms also different from GNU.

There are no doubt MANUALS and EXAMPLES that could be found and read easily to assuage all manner of doubt.
