Compiler Directives
We have already seen how to declare objects using the declarative directives
:FCT
,
:PTR
,
:INT
,
:LONG
,
:FLOAT
,
:DOUBLE
, and
:CHAR
. There are
other directives as well that control other aspects of building an application.
Table 22-8 summarizes some general purpose directives.
/* Ploting library */
/******** internal objects *******/
:STATIC 1
:FLOAT xMin 0 xMax 0
yMin 0 yMax 0
:FCT FindRange { ... }
DrawAxes { ... }
PlotPoints { ... }
/****** external objects *******/
:STATIC 0
PUB GenPlot {
:PTR xData
:PTR yData
:PTR xLabel
:PTR yLabel
...
}
Figure 22-15. The library file of Figure 22-14 rewritten using the
:STATIC
compiler directive.
Table 22-8. General purpose compiler directives
Directive Argument Use
:PRINT string Prints a string to the display during compile.
:SEARCH string Add a directory to those being searched to satisfy INCLUDE direc-
tives.
:INCLUDE string Compile an external file as part of this application.
:STATIC 1 or 0 When on, all subsequently defined objects in the current file are
STATIC.
:IFNDEF name If the name is not defined, ok. Otherwise, skip to the ENDIF
:IFDEF name If the name is defined, ok. Otherwise, skip to the ENDIF
:ENDIF - Used with :IFNDEF and :IFDEF
