Utility for creating conversion-exit code

Use this information to learn more about creating conversion-exit code.

The command for your platform produces a fragment of code that performs data conversion on data type structures, for use in your data-conversion exit program. The command takes a file containing one or more C language structure definitions. On z/OS, it then generates a data set containing assembler code fragments and conversion functions. On other platforms, it generates a file with a C function to convert each structure definition. On z/OS, the utility requires access to the LE/370 runtime library SCEERUN.

Invoking the CSQUCVX utility on z/OS

Figure 1 shows an example of the JCL used to invoke the CSQUCVX utility.

//CVX    EXEC PGM=CSQUCVX
//STEPLIB  DD DISP=SHR,DSN=thlqual.SCSQANLE
//         DD DISP=SHR,DSN=thlqual.SCSQLOAD
//         DD DISP=SHR,DSN=le370qual.SCEERUN
//SYSPRINT DD SYSOUT=*
//CSQUINP  DD DISP=SHR,DSN=MY.MQSERIES.FORMATS(MSG1)
//CSQUOUT  DD DISP=OLD,DSN=MY.MQSERIES.EXITS(MSG1)

z/OS data definition statements

The CSQUCVX utility requires DD statements with the following DD names shown in Table 1:

Table 1. Data definition statement names and descriptions

DD statement	Description
SYSPRINT	Specifies a data set or print spool class for reports and error messages.
CSQUINP	Specifies the partitioned data set containing the definitions of the data structures to be converted.
CSQUOUT	Specifies the partitioned data set where the conversion code fragments are to be written. The logical record length (LRECL) must be 80 and the record format (RECFM) must be FB.
