Summary
- Privileges
- Dependent upon parameters to be reset
- Function
- Modifies the settings of one or more Model 204 parameters
Syntax
RESET parameter=value [,parameter=value]...
Where:
| parameter | is a Model 204 parameter. |
|---|---|
| value | is the new value of the parameter; this can be specified in various formats, as discussed in "??" Part 1.
For a numeric parameter, starting with version 7.5 of Model 204, you can specify value relative to the current value of the parameter. |
Syntax notes
- The RESET command can be abbreviated as R.
- The comma (following each value) and the equal sign (before each value) are optional.
- As noted below, an alternate form of RESET, without any parameters, causes Model 204 to prompt for a line with a series of parameter names and values.
Example
RESET ERMX=50 SUB=4 ERMX 50 Maximum number of errors SUB X'04' Substitution control
Usage notes
The RESET command changes the settings of any number of Model 204 parameters. The type of parameters that can be set (for example, system parameters, file parameters) depends upon the privileges of the user who issues the command.
RESET is often used in conjunction with the VIEW command. You can VIEW parameter settings and then decide to change them. For example:
VIEW ERMX,ERASE ERMX 50 Maximum number of errors ERASE @ X'7C' Erase-character symbol RESET ERMX=40, ERASE=96 ERMX 40 Maximum number of errors ERASE - X'60' Erase-character symbol
If no parameters are specified in the RESET command, Model 204 prompts for them, as shown in the following example:
RESET *** M204.1119: READING PARAMETERS OUTLPP=50, PGSEP=3 OUTLPP 50 Output lines per page PGSEP 3 Lines between pages
If you specify a nonexistent parameter or attempt to reset a parameter that is not resettable, Model 204 responds with the message:
*** M204.1123: PARAMETER NOT RESET = parameter
You cannot use RESET to set bits that are currently undefined by Rocket Software (see the parameter descriptions of "FISTAT: Current file status", "FOPT: File options", and "OPENCTL: Password option during file open").
For example, in an Online where the Date Time Stamp feature is not installed, if a system manager issues a RESET DTS command, the following message is displayed:
RESET DTS 0 *** M204.2740: INVALID PARAMETER DTS: DATE TIME STAMP SUPPORT NOT LINKED IN DTS 1 Date time stamp updates (1=automatic, 0=bypassed)
When it processes RESET, Model 204 ends any current User Language update unit and begins a non-backoutable update unit. If a Model 204 command non-backoutable update unit is in progress, RESET is included in that update unit. For more information about Model 204 update units, see the Model 204 File Manager's Guide.
