Condition-Block Syntax

Syntax

       
        
       
       IF (condition)
    package-body 
[ ELSEIF (condition) 
    package-body 
] 
[ ELSE 
    package-body 
] ENDIF
      

The square brackets enclose conditions within the Condition-Block statement that are optional.

Note: It is advisable to put conditions within the square brackets.

The Condition-Blocks can be used to ensure that the SIS file installs appropriate binaries for the target platform. For example:

       
        
       
       IF FPHARDWARE=0
"\epoc32\release\gcce\urel\myapp.exe"-"!:\sys\bin\myapp.exe.exe";
ELSE
"\epoc32\release\gcce\urel\myappVFP.exe"-"!:\sys\bin\myappVFP.exe";
ENDIF
      

Example

The following example illustrates the usage of Conditional-Blocks within a PKG file:

       
        
       
       ; PKG file to illustrate conditional blocks
