Syntax Conventions
The command lines (blocks) used in programming include commands, symbols,
variables, functions and/or arguments.
Aparticularsyntaxisusedforeachoftheelementsdescribedherein. Theapplicable
syntax rules describe how to write the programme blocks.
Certain syntaxes are given on one or more lines. Writing is simplified by use of the
following conventions:
- the functionality(ies) to which the syntax relates is (are) highlighted by the use of
bold face characters,
- «..» or lower case letters after one or more capital letters, addresses or signs
replace a numerical value (e.g. N..),
- the ellipsis «...» replaces a character or address string similar to that preceding it
in the block (e.g. [Symb1]/[Symb2]...),
- «xx» after one or more address letters replaces alphanumeric characters (e.g.
[.IBxx(i)]),
- «xxx» after an address letter replaces numerical values (e.g. Gxxx).

Structured Programming
en-938872/2 1 - 3

The system provides the possibility of programming structured branches and loops,
makingthe programmes easier to read and simplifyingthe programming of complex
part programmes.
The programming tools described in this chapter are used to create subroutines
called by G functions (see Chapter 5).
1.1 General
A structured sequence always begins and ends with keywords.
It begins with one of the following keywords:
IF
REPEAT
WHILE
FOR
It ends with:
ENDI for IF
UNTIL for REPEAT
ENDW for WHILE
ENDF for FOR
The word ELSE can be interposed between the words IF and ENDI.
1.1.1 Commands Used in Structured Sequences
- Conditional execution of instructions: IF, THEN, ELSE, ENDI
- Repeat until loops: REPEAT, UNTIL
- While loops: WHILE, DO, ENDW
- Loops with control variables: FOR, TO, DOWNTO, BY, DO, ENDF
- Exit from a loop: EXIT
1.1.2 General Syntax Rules
ThewordsIF, REPEAT, WHILE, FOR, ENDI, UNTIL, ENDW and ENDF mustbethe
first words in a block (no sequence number).
The words IF, REPEAT, THEN, ELSE, UNTIL, WHILE, DO and DOWNTO must
always be followed by a space, e.g.:
WHILEL0 <3 is not recognised by the system. The required syntax is WHILE L0 <3.
ThewordsDOandTHENmustimmediatelyfollowthecondition. Alternately,ifthese
two words are not located on the same line as the words IF, WHILE and FOR, they
must be the first words on the next line.

1 - 4 en-938872/2
Blocks with sequence numbers (N..) are allowed in loops.
Blocks beginning with the words ENDI, ENDW, ENDF, EXIT or UNTIL must not
include ISO programming functions.
One of words DO, THEN or ELSE can be followed by ISO programming functions in
a same block.
Example:
WHILE L1 < 3 DO G91 X12
or
WHILE L1 < 3
DO G91 X12
The following sequence is refused:
WHILE L0 < 3 G91 X10
DO Not allowed in a
conditional instruction

1.1.3 Nesting and Branches
Nesting
Fifteen structured nesting levels are possible independently of subroutine calls by
function G77 ...
Example:
First nesting level Second nesting level Third nesting level
IF IF
ENDI UNTIL
REPEAT
ENDI
Branches
Programming of a conditional or unconditional branch by G79 ... is allowed in a
structured sequence, but must branch to the lowest nesting level of the current
programme or subroutine.
Example:
%1 %2
IF G79 N100 good
WHILE REPEAT
G79 N100 good IF
G77 H2 G79 N100 good
G79 N50 bad G79 N50 bad
G79 N30 bad ENDI
N30 N50
ENDW UNTIL
N50 N100
ENDI

1.2 Structured Programming Commands
1.2.1 Condition Graph
Acondition must follow one of words IF,WHILEorUNTIL and must be located in the
same block. If the block contains limits and a possible increment, they must follow
the word FOR.

Variables: All the variables used in parametric programming:
L variables, E parameters and symbolic variables.
Expression: Sequence of parameters and immediate values connected by symbols
+,-,*,/,!,&(seeChapter6oftheProgrammingManual). Theoperations
are calculated in sequence from left to right.
