FASBOL is a compiler for SNOBOL4; the documentation is found 
in FASBOL.MJC[UP,DOC].  SNOBOL4 itself is documented in "The
SNOBOL4 Programming Language", 2nd ed., by Griswold, Poage,
and Polonsky, Prentice-Hall, 1971.
To run, type R FASBOL, then answer to the asterisk:
	<fail file>←<source file>
FASBOL puts the assembly language program it generates into 
<fail file>, which has default extension .FAI, and then 
automatically swaps to FAIL to translate the compiled code,
creating in the process a .REL file with the same name as
<fail file>.  To execute the program, type EX <file> .
