1. Pre-processor setup

The OSAI 10 Series 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 OSAI 10 Series 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.

2. Register default value

The OSAI controller accept to specify codes and registers without a numeric value when 0 is to be used. The pre-propcessor will expand them back with the 0 value in order for the CE questionnaire to match the registers properly.

Exemple of NC blocks before and after being pre-processed:

GX34	G0 X34
G92 XY	G92 X0 Y0

3. Operators

=	Is equal
<>	Not equal
>=	Greater or equal then
>	Greater than
<=	Less or equal than
<	Less than
AND	Logical AND
OR	Logical OR
NOT	Logical NOT

4. Arithmetic operators

Syntax	Description
-	Subtraction
+	Addition
*	Multiplication
/	Division
=	Assignation
( )	Priority
SIN(x)	Sinus
ARS(x)	ArcSinus
COS(x)	Cosinus
ARC(x)	ArcCosinus
TAN(x)	Tangent
ART(x)	ArcTangeant
SQR(x)	Square root
ABS(x)	Absolute value
INT(x)	Integer part
NEG(x)	Negative
MOD(x,y)	Modulo (get tde remainder part)

5. Unconditional branching

Syntax	Description
(GTO,<label>)	Jump to a specific label in the MCD. (GTO,label) (GTO,?SC12.5) Label are defined between double quotes (i.e. "LABEL")

6. Conditional branching

Syntax

Description

(IF,<condition>)
(ELSE)
(ENDIF)

Evaluate boolean condition and process if condition is TRUE. Otherwise skip to (ENDIF) or (ELSE) block.

(IF,E3 <> 2)
...
(ELSE)
...
(ENDIF)

7. Repetition

Syntax	Description
(EPP,<label1>,<label2>)	Execute the blocks in the range <label1> to <label2>
(RPT,<count>) (ERP)	Execute the blocks between the RPT and ERP function <count> amount of times

8. Variables

Syntax	Description
E<n>	E numeric parameters
L<n>	L numeric parameters
!name_var[<index>].[number of characters]CH	User text variables
!name_var[<index>]	User numeric variables
SN<n>	System numeric variables
SC<index>.<length>	System text variables
H<n>	Paramacros numeric variables
HF<n>	Paramacros logical variables indicating if the associated H variable is used
HC	Paramacros text variable

10. Other matching patterns

Syntax	Description
(DIS,<message>)	Operator messages
;	End of block marker and start of comments
N<n>	Sequence number
/	When appearing at the start of a block or after the sequence number, treated as block skip.

Syntax	Description
(CLS,<file>) (CLD,<file>) (CLT,<file>)	Subprogram call with direct file with optional path
(PTH,<mode>,<path>)	Preset path for CLS, CLD and CLT calls
G300-G699	Non-modal PARAMACRO calls with optional parameters
G700-G998	Modal PARAMACRO calls with optional parameters
G999	Modal PARAMACRO cancel code
