This article describes the general syntax and behavior of the text parser.

REVISION = numberThis numeric value is used to decide, how the following sections are read and handled. This may be important if the tools change the syntax and/or semantics. Any section may have a parameter
@REVISION = numberto change the revision number only for the current section.
If an external tool add some sections at the end, they should first declare
Example:
[NAME] # Use syntax and semantics of tools revision 1234 for this section @REVISION = 1234 # Calculated check points ...→ Define and calculate global values in the
The local name space is cleared every time when a new section begins. Variables of the global name space are held until the complete scanning and parsing is done.
Predefined constants are definition set by the parser.
The user can add user constants by using the command line option
»--const name1=val1,name2=val2,...« (or
Some sections define automatically global variables for cross section links.
The user can define private, local and global variables.
Syntax:
@DEF NAME [['?']'=' EXPRESSION] [, NAME= ...]... @PDEF NAME [['?']'=' EXPRESSION] [, NAME= ...]... @LDEF NAME [['?']'=' EXPRESSION] [, NAME= ...]... @GDEF NAME [['?']'=' EXPRESSION] [, NAME= ...]...
An extension immediately behind the DEF command force the storing type:
It's also possible to define enumerated and shifted values with:
The old commands @NUM, @GNUM, @INT, @GINT, @FLOAT and @GFLOAT are still allowed for compatibility reasons as alternatives for @DEF, @GDEF, @DEF.I, @GDEF.I, @DEF.F and @GDEF.F.
Examples:
@def.i my_item = 0x0a + 3 @gdef.f origin ?= 123.4, origin2 = origin/2 @ldef $a.num = -12.3
If a vector with name
If decoding a text file the scanned index names may be used for the new output.
Syntax:

Signs are calculated from right to left:

Don't change the value. | |
Mathematical negation. | |
Logical negation. The result is either 0 (FALSE) or 1 (TRUE). | |
Bitwise negation. The result is always an integer. |
A Bitfield is an easy way to set bits in an integer. For example value <2,4:6> is an integer with bits 2 and 4..6 set (=0x74).

The general syntax:
Syntax: "%" [ index "$"] [flags] [fw] ["." prec] [modifier] conv
The arguments are automatically converted to the requested data type. By default, the arguments are used in the order given, where each '*' (see Field width and Precision below) and each conversion specifier asks for the next argument. One can also specify explicitly which argument is taken, at each place where an argument is required, by writing "%m$" instead of '%' and "*m$" instead of '*', where the decimal integer m denotes the position in the argument list of the desired argument, indexed starting from 1.

Example 2:
@macro sum @pdef sum = 0 @for i=1;$n @pdef sum = sum + param(i) @endfor @return sum @endmacro @:sum(1,2,3,4) @assert result() == 10
The new function takes precedence over already defined user and system functions with the same name.
