Invocation and Precompiler Options - (Windows - C)

Option and Option Name

Description

Default

-a catalog name

If a table name exists multiple times in the CDD and is not fully qualified with CATALOG.SCHEMA.TABLE, an  'ambiguous table reference' error will occur.

The default catalog name can be supplied with '-a <catalog_name>'.

The catalog name must exist in the CDD.

-b suppress trailing blanks

Suppress character string trailing blanks.

Character string Host-Variables used for input or output are padded with trailing blanks as required.

Trailing blanks can be suppressed with '-b'.

This is especially useful for applications written in C/C++. where it is normal practice for character strings to be NULL terminated without trailing blanks padding.

no

-c compatibility mode

The Precompiler executes in extended ACE mode.

ANSI mode can be enabled with '-c ANSI'.

This option affects messages only. In ANSI mode, SQL syntax which does not adhere to ANSI standards will be flagged as a warning.

Code generation is not affected.

Values : ACE / ANSI

ace

-e error listing file

Error, Warning and Statistics messages are written to STDOUT. These messages can be routed to an output file with '-e <error listing file>'.

The <error listing file> name must consist of at least a basename and optionally an extension. If no extension is supplied, the default extension 'pcl' will be used.

On z/OS platforms, a DDNAME must be used instead of a filename, using the format :

  -e //ddn:ddname

The DDNAME assignment must be made to a physical file. It must not be assigned to // DD SYSOUT=

<basename>.plc (Windows and Open Systems)

  DD=SYSTERM (z/OS)

-f code output file

The <code output file> name must consist of at least a basename and optionally an extension. If no extension is supplied, the default extension 'cbl' will be used.

 <basename>.c

-k keep the generated output file in case of compilation errors

The <code output file> is deleted after compilation errors.

The <code output file> can be kept with '-k'.

no

-l generate line information

Line information in the form :

  /* line nn "<source file name>" */

is generated into the <code output file> with '-l'.

This can be useful when you want to know the line number of the associated SQL Statement in the original C/C++ source file.

no

-m migration check of SQL statements  only

The Precompiler executes in code generation mode. When migrating or checking existing C/C++ or COBOL programs, it can be useful to have a listing of the SQL statements only. These are output to STDOUT. No output file is generated.

The migration check can be enabled with '-m'.

no

-n Adabas SQL Gateway server name

This option is REQUIRED

Server <server_name> to which the session is to connect.

<server_name> need not be enclosed in quotes.

no default

-o output code mode

Output code mode is either 32 or 64-Bit

The C/C++ Precompiler generates 32-Bit code when invoked on 32-Bit systems (-o 32) and 64-Bit code when invoked on 64-Bit systems (-o 64).

Generation of code suitable for a different environment can be enabled with '-o 32' or '-o 64'.

Values  : 32 / 64

32 (when invoked on 32-Bit systems)

64 (when invoked on 64-Bit systems)

-q no SQL validation

The Precompiler performs SQL syntax validation at precompile time.

SQL validation can be disabled with '-q'.

no

-r length of output line

The Precompiler generates code output files with a line length of 72.

The output line length can be increased to the length defined in <output line length>.

The output line length cannot be defined shorter than the default length for the appropriate Host Language. If this is attempted, the output line length will be reset to the appropriate Host Language default and a warning message issued.

Values  : >= 72

72

-s schema name

The SCHEMA name used by the Precompiler is derived from <user_name> as supplied with the '-u' option.

The default schema name can be overridden with '-s <schema_name>'.

The schema name must exist in the CDD.

user_name

-u user name [, password]

This option is REQUIRED

User <user_name> and Password <password> to be connected to the Server defined with '-n'.

The <password> parameter is optional, however, this must be supplied if the user being connected requires a password.

no default

-w working directory

Input and output files are searched for or stored in the current directory. This can be overridden with '-w <working directory>'.

If no filename is given for a file to be generated, the basename of the precompiler source file will be taken, with the appropriate extension.

current directory

-z suppress warnings

Warning messages are generated by the Precompiler.

Warning messages can be suppressed with '-z'.

This option affects WARNING messages only. ERROR messages cannot be suppressed.

no

-@ file containing command line options and parameters

Command line options and parameters saved in a file can be optionally input to the Precompiler with '-@ <command line options and parameters file>'.

The options and parameters in the <command line options and parameters file> can be combined with other command line options when invoking the Precompiler.

On z/OS platforms, a DDNAME must be used instead of a filename, using the format :

  -@ //ddn:ddname

The DDNAME assignment must be made to a physical file. It must not be assigned to // DD *

no default
