Files and records

Macro	Brief description
CUPAB	Generates addressing aids (DSECTs) for the operand lists of the RDATA, WROUT and WRTRD macros
GCCSN	Displays the current coding table for command and data input (SYSDTA/SYSCMD)
RDATA	Reads a record from the SYSDTA system file, i.e. from a cataloged file, an S variable, a PLAM library element or the interactive terminal (see also CUPAB)
VTSUCB	Creates VTSU parameters for input/output
WRLST	Causes a record to be written to the SYSLST system file and/or the SYSLST01, SYSLST02, ... ,SYSLST99 system files. The relevant system file is printed after the job has terminated, provided the user has not directed it to a cataloged file
WROUT	Causes a record to be written to the SYSOUT system file, i.e. in interactive mode to the terminal, a cataloged file, an S variable or a PLAM library element. In batch mode the SYSOUT system file is printed after job termination (see also CUPAB), unless the user has assigned it to a cataloged file, an S variable or a PLAM library element
WRTRD	In interactive mode, writes a message to the terminal and subsequently accepts a message from there (see also CUPAB)
