CL Command Reference - OVRDSPF
CL Command List > OVRDSPF Reference
Description:
The Override with Display File (OVRDSPF) command is used to: (1) override (replace) the file named in the program, (2) override certain parameters of a file that are used by the program, or (3) override the file named in the program and override certain parameters of the file processed. Parameters overridden by this command are specified in the file description, in the program, or in other called file override commands.
If a file named in the program is overridden, the name of that file is specified in the FILE parameter and the name of the overriding file (the file being processed) is specified in the TOFILE parameter. The OVRDSPF command also specifies parameters to override values contained in the file description of the overriding file. If the file named in the program is not replaced but certain parameters of the file are overridden, the name of the file is specified in the FILE parameter and *FILE is specified in the TOFILE parameter. The parameters overridden are then specified by the other parameters of the OVRDSPF command. Parameters that are not specified do not affect parameters specified in the file description, in the program, or in other called file override commands.
Note: Using this command does not cause a file to be overridden immediately. Information provided on this command is stored until the file is used, at which time the file is overridden.
Examples:
OVRDSPF FILE(DISPLAY75) WAITFILE(30)
This command overrides the file wait time value specified in the DISPLAY75 device file description, in the program, or in other called OVRDSPF commands. The program in which this command occurs waits up to 30 seconds (if necessary) to allocate the required file resources to the file named DISPLAY75.
