Oh Dear – it seems the\u00a0#ELSE\u00a0feature is currently broken in SPLat\/PC.\u00a0 As a work-around, you can use ELSEIF like this:

#IF EQ( YourThing )
; if TRUE
#ELSEIF EQ( 1, 1 ) ;ELSE is broken, so this is a workaround (it’s always TRUE and will only execute if everything prior is FALSE)
; otherwise
#ENDIF

If you’re using builder, then\u00a0Builder Conditional Segments<\/a>\u00a0do work.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

From build 327 SPLat\/PC supports conditional code translation. What this means is that your .spt source file(s) can contain statements that control which lines actually get included in the final program. NOTE:<\/strong> These instructions do not work at RUN TIME<\/strong>, they are only used when COMPILING<\/strong> your SPLat program, so they allow you to include different pieces of code when compiling.<\/p>\n\n\n\n


Example:

Board: #EQU MMI

#IF EQ(Board, MMI)
iStart EQU 7
oMotor EQU 0

#ELSEIF EQ(Board, MS)
iStart EQU 15
oMotor EQU 10

#ELSE
 Board type not defined

#ENDIF
<\/code><\/pre>\n\n\n\n
What’s happening here?<\/p>\n\n\n\n
The first line defines “Board” as an #EQU<\/code> constant with the value MMI (as a string). The second – #IF<\/code> – line says “If Board = MMI” then use the lines that follow. Those lines allocate an input and an output. The EQ(..,..)<\/code> is called a qualifying function, which must always evaluate to True or False.  Then comes the #ELSEIF<\/code>. It says “If the MMI test failed, try for MS instead”. If that test passes, then a different set of allocations will be used. The final #ELSE<\/code> trips if neither the MMI nor the MS test passes, and results in an error, so the program translation will fail.<\/p>\n\n\n\n
As it stands the example will use MMI values. But I only have to edit one line, the very first one, to switch to allocations for (presumably) an MS121.<\/p>\n\n\n\n
Conditional translation hash functions<\/h6>\n\n\n\n
There are four conditional translation hash functions:<\/p>\n\n\n\n

#IF
#ELSEIF
#ELSE
#ENDIF
<\/pre>\n\n\n\n
A number of rules apply:<\/p>\n\n\n\n
    \n
  1. They must appear in the order listed.<\/li>\n\n\n\n
  2. #ELSEIF<\/code> and #ELSE<\/code> are optional<\/li>\n\n\n\n
  3. There can be more than one #ELSEIF<\/code> but never more than one #ELSE.<\/code><\/li>\n\n\n\n
  4. #IF<\/code> and #ELSEIF<\/code>  must have one and only one qualifying function<\/em>. That’s what determines if the condition will apply.<\/li>\n\n\n\n
  5. #IF ... #ENDIF<\/code> blocks may be nested wholly within each other<\/li>\n\n\n\n
  6. The #EQU constants used in the qualifying function must be defined before the #IF block.<\/li>\n<\/ol>\n\n\n\n
    Qualifying functions<\/h6>\n\n\n\n
    There are a number of qualifying functions that can be use with #IF<\/code> and #ELSEIF<\/code>. The arguments can be text strings or numbers, or #EQU defined constants that represent text strings or numbers. Some qualifying functions work on text strings, some on numerical values. The following tables summarises them.<\/p>\n\n\n\n
    Function<\/td>What it does<\/td>Example<\/td><\/tr>
    EQ(A,B)<\/code><\/td>Tests if two #EQUated constants are equal. If they can both be interpreted as numbers, the comparison is performed on the numerical values.

     The #EQU<\/code> constants used in qualifying functions must be defined before they are used.<\/p>\n","protected":false},"excerpt":{"rendered":"
