Adabas Pre-Compiler works in conjunction with Predict. Predict uses the file and field definitions for generating the data structures used for communicating with the database. The programmer does not need to be concerned about the declaration of the fields. Adabas Pre-Compiler also generates active cross-reference external subroutines and used copy codes. This information may be retrieved by the Predict LIST XREF for 3GL function.

The source program produced from an Adabas Pre-Compiler run, consists of a COBOL or PL/I program with direct call statements, similar to a direct-call program. The original Adabas Pre-Compiler statements also appear and precede the related direct call statements. They appear as comments for ease of reference, as they in no way affect the COBOL or PL/I compiler.

For detailed information about Adabas direct calls, see Adabas for Mainframes > Command Reference > Calling Adabas.
