1. Pre-processor setup

The Mazak EIA/ISO pre-processor can be setup in order to be a little bit more flexible. This is done via the macro function $FCEPP( ). This function’s purpose is really to communicate information that are specific to some pre-processor without being standard on every one of them. These are the configuration parameter supported by the pre-processor.

• $FCEPP('PROCESS', 'COMMENTS', value )

Value: $TRUE to let the pre-processor process the comments (this is the default).

$FALSE to have the pre-processor leave the comments as-is on the blocks.

• $FCEPP('PROCESS', 'MESSAGES', value )

Value: $TRUE to let the pre-processor process the operator messages(this is the default).

$FALSE to have the pre-processor leave the operator messages as-is on the blocks.

2. Command Abbreviations

The following commands can be coded by specifying at least 2 or more characters instead of the whole command name.

• THEN

• GOTO

• WHILE

• END

• SIN

• ASIN

• COS

• ACOS

• TAN

• ATAN

• SQRT

• ABS

• ROUND

• FIX

• FUP

• EXP

• AND

• XOR

3. Operators

• EQ Is equal

• NE Not equal

• GE Greater or equal then

• GT Greater than

• LE Less or equal than

• LT Less than

• AND Logical AND

• && Logical AND

• OR Logical OR

• || Logical OR

• XOR Bitwise OR

4. Arithmetic operators

	Subtraction
	Addition
*	Multiplication
/	Division
=	Assignation
[ ]	Priority
SIN[x]	Sinus
ASIN[x]	ArcSinus
COS[x]	Cosinus
ACOS[x]	ArcCosinus
TAN[x]	Tangent
ATAN[x]	ArcTangeant
SQRT[x]	Square root
ABS[x]	Absolute value
ROUND[x]	Rounding value
FIX[x]	Nearest integer part closest to 0
FUP[x]	Nearest integer part farthest to 0
LN[x]	Logarithm
EXP[x]	Exponential value
MOD[x]	Modulo (get the remainder part)

5. Unconditional branching

Syntax	Description
GOTO	Jump to a specific sequence number in the MCD. GOTO 150

6. Conditional branching

Syntax	Description
IF	Evaluate boolean condition and optionally branch. IF [ [212]EQ[442|2*12]EQ[44/2] ] GOTO30; IF [#2GT5.5] THEN #4=#2
IF/ELSE/ENDIF	Evaluate boolean condition and execute block of codes. IF [ [212]EQ[442|2*12]EQ[44/2] ] THEN G0 X100. ENDIF

7. Repetition

Syntax	Description
WHILE [expr] DO n ... END n	Execute a portion of blocks between the WHILE and END as long as the expression is true. The DO number and END number must match to form a valid WHILE block. WHILE [#3 GT 15] DO 1 G0X#3 #3=#3-1 END 1

8. Variables

Syntax	Description
#n	Variables are defined starting from 1 (#n) #1, #45, #123, ...

9. Sub-program related

Syntax	Description
G65	Call subprogram non-modal (won’t repeat) and use a new local variable stack. This call can have variable parameters. G65 P9000 L1 A20. B34.56 G65 <DRILL2> L1 A20. B34.56
G66	Call subprogram modal (will repeat on every motion block until a G67 is encountered). Also create a new local variable stack. G66 P9000 L1 A20. B34.56 G66 <DRILL2> L1 A20. B34.56
G66.1	Call subprogram modal (will repeat on every block until a G67 is encountered). It reads macro parameters on every block. Also create a new local variable stack. G66.1 P9000 L1 A20. B34.56 G66.1 <DRILL2> L1 A20. B34.56
G67	Stop any modal subprogram calling.
M98	Call a subprogram non-modal (won’t repeat). And variable stack stay the same. All the current variables will be accessible from the subprogram. Because of this, no parameters can be passed to the subprogram. M98 P9000 L2 M98 <FACE2> L2
M198	Same as M98 M198 P9000 L2 M198 <FACE1> L2
(Other)	Subprogram calling using G,M,T,S,B and other supported addresses is available. Please consult the Mazak EIA/ISO programming manual under the "CUSTOM MACROS" section. It is recommended to use the program startup macro to set the required variables (parameters) via EXEC command calls.
M99	End current subprogram.
P[0-9]+	Specify the subprogram number to call. G65 P9002
<file-name>	Specify the subprogram file to call. Also specify the beginning of a subprogram. G65 <SUBPROG> <SUBPROG>
O[0-9]+	Specify beginning of program/subprogram O9002
L[0-9]+	Specify repeat count to the subprogram. L0 means 1 execution and is the default. So L1 means 1 repeat (2 execution). G65 P9002 L1 G65 <FACE3> L1

10. Other matching patterns

Description	Description
(Comments)	Comments. Text enclosed between ( ) (this is a comment)
;	The “;”marks the end of a block. Everything after it is ignored N12 G0 Z120.5; After end of block
