Direct Files in "Native"

Q: Is there a way to create direct files using CL commands? I'm used to creating RETAIN-J direct files in the S/36 environment but can't seem to "nativize" it. - Tim Phinney

A: It takes two commands: Create Physical File (CRTPF) and Initialize Physical File Member (INZPFM). You run the CRTPF command as usual (supplying either the record length in the RCDLEN parameter, or using DDS). Then you run the Initialize Physical File Member (INZPFM) command to initialize a certain number of records, as in:

 INZPFM FILE(lib/file) + RECORDS(*DFT) + TOTRCDS(1000)

This command creates 1000 records in the "direct" file, initializing them to their default values (blanks for alphanumeric fields, zeros for numeric fields). RECORDS(*DLT) initializes all 1000 records to deleted records.

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
