PARAM Command
*
specifies that all run-time messages are to be discarded.
TAPE-DIALOGUE
applies only to the non-CRE environment, in which it sets (ON) or clears (OFF) 
the tape dialogue. If the tape dialogue is cleared, the tape assigned in either 
the SELECT clause, TACL ASSIGN directive, or DEFINE is assumed to be the 
correct tape. No dialogue appears for any tape, whether or not NO REWIND is 
specified; however, if a reel swap occurs, the tape dialog appears for that file 
connector.
PRINTER-CONTROL
specifies that the operating environment must return control to the program 
when the printer specified by the cobol-file-name is not ready or is out of 
paper.
cobol-file-name
is the FD name of a file in a COBOL program (not the operating system file 
name or a DEFINE name).
When the PRINTER-CONTROL parameter is absent, the HP COBOL run-time 
routines provide automatic handling for printer fault conditions, without control 
returning to the program until the printer is again made ready.
parameter-name
is a parameter to be handled through the SMU. For information on the SMU, 
see Saved Message Utility (SMU) Overview.
parameter-value
is the value to be given to parameter-name. 
Usage Considerations:
•
WAITED-IO and HP COBOL Fast I-O
If a program for which WAITED-IO was specified attempts to open a file for 
HP COBOL Fast I-O, sequential block buffering of buffered cache is used instead, 
degrading performance by a factor of five to ten.
Note. To see what parameters are currently defined, enter just PARAM followed by a 
carriage return.
