fglxslp

When migrating from Genero Application Server (GAS) 1.3x to 2.00, it is necessary to update your GAS configuration file to conform to the XML specifications of GAS 2.00. A migration tool, fglxslp, has been added to assist you in this migration.

Usage:

$FGLASDIR/bin/fglxslp $FGLASDIR/etc/gasxcf1xxto200.xsl $FGLASDIR/etc/as-132.xcf > $FGLASDIR/etc/myas.xcf

Notes:

fglxslp is the migration tool.
gasxcf1xxto200.xsl is the XSL style sheet that describes the GAS 2.00 XML configuration file
as-132.xcf is the configuration file to migrate (GAS 1.3x).
myas.xcf is the result (new configuration file for GAS 2.00).

fglxmlp

The XML Preprocessor can be used as part of the BDL development process. It fetches data in a XML resource file to “fill” the content of a source file that contains the dollar tag expression.

Usage:

$FGLASDIR/bin/fglxmlp -i src1.4gx -o src1.4gl -r resource.xrf

Notes:

src1.4gx is the file to be processed through the XML Preprocessor.
src1.4gl is the output file.
resource.xrf is the XML resource file containing the definition of a complex 4GL record.

Using the XML Preprocessor

In this example, two source files will be "expanded" through the XML resource file. The resource file contains the definition of a complex 4GL record. The extension of files to be processed through the XML Preprocessor is .4gx. The extension for the resource file is .xrf (XML Resource File).

     fglxmlp -i src1.4gx -o src1.4gl -r resource.xrf

     fglxmlp -i src2.4gx -o src2.4gl -r resource.xrf

The resulting.4gl files are compiled and link as usual:

     fglcomp -c src1.4gl

     fglcomp -c src2.4gl

     fgllink -o project.42r src1.42m src2.42m

Files used in the example

src1.4gx :

01 FUNCTION useRecord (myRecord)
02    DEFINE myRecord $(record)
...
06 END FUNCTION

resource.xrf :

01 <?xml version="1.0" ?>
02
03 <RESOURCE_FILE>
04   <RESOURCE_LIST>
05     <RESOURCE Name="record"><![CDATA[
06       RECORD
07         nb_columns INTEGER,
08         nb_lines INTEGER,
09         name CHAR (8)
10       END RECORD
11     ]]></RESOURCE>
12   </RESOURCE_LIST>
13 </RESOURCE_FILE>

The output file src1.4gl :

01 FUNCTION useRecord (myRecord)
02   DEFINE myRecord
03       RECORD
04         nb_columns INTEGER
05         nb_lines INTEGER,
06         name CHAR (8)
07       END RECORD
...
15 END FUNCTION
