<h1 class="topictitle1"> Use directives in ILE RPG applications that use SQL</h1>
|
||
|
|
<div><p>RPG directives are handled by the SQL precompiler according to
|
||
|
|
the value of the RPG preprocessor options parameter (RPGPPOPT). If the RPG
|
||
|
|
preprocessor is used, the SQL precompile will run using the expanded preprocessed
|
||
|
|
source.</p>
|
||
|
|
<div class="section"> <ul><li>When the value is *NONE, the RPG preprocessor is not called to preprocess
|
||
|
|
the RPG source. The only directive handled by the SQL precompiler is /COPY.
|
||
|
|
Nested /COPY statements will not be handled. All other directives will be
|
||
|
|
ignored until the RPG compiler is called. This means that all RPG and SQL
|
||
|
|
statements within conditional logic blocks will be processed unconditionally
|
||
|
|
by the SQL precompiler. </li>
|
||
|
|
<li>When the value is *LVL1, the RPG preprocessor will be called to preprocess
|
||
|
|
the RPG source. All /COPY statements are expanded, even nested
|
||
|
|
/COPY statements, and the conditional compilation directives will be handled.</li>
|
||
|
|
<li>When the value is *LVL2, the RPG preprocessor will be called to preprocess
|
||
|
|
the RPG source. All /COPY and /INCLUDE statements are expanded and the conditional
|
||
|
|
compilation directives will be handled.</li>
|
||
|
|
<li>When *LVL1 or *LVL2 is used, there is a possibility that the expanded
|
||
|
|
source generated by the RPG preprocessor will become very large and reach
|
||
|
|
a resource limit due to the expansion of the /COPY and /INCLUDE statements.
|
||
|
|
If this happens you must either break up your source into smaller pieces,
|
||
|
|
or not use the RPG preprocessor.</li>
