SAAL Format: LABEL OPC OPERAND1, OPERAND2, OPERAND3 * comment
Lines beginning with * are comments. Operand fields are comma-separated. Whitespace is flexible.

Memory Map (961 chars):

Symbol	Range	Use
CARD	000–079	Card read buffer (80c)
PRT	080–211	Print line buffer (132c)
PCH	212–291	Card punch buffer (80c)
WORK	292–960	Program + working storage

Instructions (each occupies 12 chars in core):

Op	Operands	Effect
LDA	addr	A ← M[addr]
STA	addr	M[addr] ← A
ADD	addr	A ← A + M[addr] (digit, sets OV)
SUB	addr	A ← A − M[addr] (digit)
ADF	src,dst,len	M[dst..] ← M[dst..] + M[src..] (BCD field)
SBF	src,dst,len	BCD field subtract
MVC	src,dst,len	Move len chars
CLR	addr,,len	Fill len chars with space
CMP	a,b,len	Compare fields, set EQ/LT/GT
INC	addr,,len	Increment BCD field by 1
DEC	addr,,len	Decrement BCD field by 1
JMP	addr	P ← addr
JEQ	addr	Jump if EQ flag
JNE	addr	Jump if not EQ
JLT	addr	Jump if LT flag
JGT	addr	Jump if GT flag
JOV	addr	Jump on overflow (clears flag)
JEF	addr	Jump on End-of-File from card reader
RDC	—	Read next card into CARD; sets EOF if hopper empty
PRT	—	Print PRT buffer, clear, advance paper
PCH	—	Punch card from PCH buffer, clear
HLT	—	Halt processor

Directives:

ORG addr	Set assembly origin (default 292)
LBL EQU n	Define symbol = numeric value
LBL DC 'TEXT'	Define char constant(s)
LBL DC 12345	Define numeric digits
LBL DS n	Reserve n spaces
END	End of source

Operand forms: a number (e.g. 080), a symbol (CARD), or symbol+offset (CARD+5). Use empty operand for unused fields: CLR PRT,,132
