START (ST)
START (ST)
Depending on the target host type, this command enables an Ispec or Report to start:
$ An MCP based WFL Job
$ An OS 2200 based ECL runstream
$ A UNIX executable shell script in the background.
$ A .EXE, .COM or .BAT file in Windows NT or Windows 95.
Use of this command with OLTP is described in your LINC Generate Operations Guide.
Specific details for each target host type are given in the following subsections.
For an MCP based LINC System
The START; command enables an Ispec or Report to execute a WFL Job with parameters.
If the parameter item is a Setup.Data item or a screen item, it must include quotation
marks, or the WFL will fail. The WFL Job File should be located on the Object pack family,
or on the alternative (OTHERWISE) pack for the system usercode. It is your responsibility
to provide a valid parameter as required by the Job.
Files started in this way will not be attached to (or controlled by) the LINC System.
The START; command has the following parameters:
$ A literal or data item giving the 32-character Work Flow Job file. This parameter is
compulsory.
$ A literal or data item value (not exceeding 200 characters), being a file equate or a WFL
string parameter value. This parameter is optional.
If the length of the first parameter and the length of the second parameter both exceed 18,
data items must be used (not literals).
If the file equates, Accept command, or string parameter is invalid, MCP will reject the
START; command, the program or job will not be started, and the LINC logic will not
receive notification of the error.
GLB.STATUS is set to indicate the result of the START; command, as shown in the
following table.
Value Result Indicated
INVAL The program or job name is invalid or cannot be located.
Space The MCP has been instructed to start the program or job.
