Device Functions

Device functions specify interactive programs of a number of types and report programs. These programs consist of either a panel design or report design and an action diagram. Device functions are external functions with the exception of Print Object (PRTOBJ), which is an internal function. You implement device functions as programs that operate over databases. The device functions are:

• Display Record (DSPRCD)
• Display Record 2 panels (DSPRCD2)
• Display Record 3 panels (DSPRCD3)
• Prompt Record (PMTRCD)
• Edit Record (EDTRCD)
• Edit Record 2 panels (EDTRCD2)
• Edit Record 3 panels (EDTRCD3)
• Display File (DSPFIL)
• Edit File (EDTFIL)
• Select Record (SELRCD)
• Display Transaction (DSPTRN)
• Edit Transaction (EDTTRN)
• Print File (PRTFIL)
• Print Object (PRTOBJ)
