A or M can be coded with any record format, such as: RECFM=FBA
A indicates that the record contains ISO/ANSI device control characters.
M indicates that the records contain machine code control characters.
Here, you can read for yourself: Coding RECFM for BSAM, EXCP, and QSAM Access Methods

RECfm=format Specifies the record format of a data set. Valid record formats are: F, FA, FB, FBA, FBM, FM, U, V, VA, VB, VBA, VBM, and VBS. These record formats have the following meanings:

F Fixed record length
V Variable record length
U Undefined record length
B Blocked records
S Spanned records
A Records contain ISO/ANSI control characters
M Records contain machine code control characters.

FB - fixed block
FBA same but contains ISO/ANSI control characters
FBM contains machine code control characters
