!Statusl Description ISymbolic unit for the console used for this I file. IName of I/O area. ILength in bytes of I/O area (for PUTR macro
usage, length of output part of I/O area). I If RECFORM=UNDEF, maximum is 256. If I omitted, 80 is default. ILength in bytes for input part of I/O area I for PUTR macro usage. ILogic module name for this DTF. If omitted, I IOCS generates a standard name. I IThe logic module is generated as part of I the DTF. I (FIXUNB or UNDEF). If omitted, FIXUNB is I default. IRegister number if RECFORM=UNDEF. General I registers 2 through 12, enclosed in I parentheses. I (I NPUT, OUTPUT, or CMBND). Input processes I both input dnd output. CMBND must be I specified for PUTR macro usage. If omitted, I :NPUT is default. IGET or PUT specifies work area.
