Output from BS2000 SHOW commands to S variables:
Output from SHOW commands is rerouted to S variables. These serve as filters between BS2000 command and output servers. Thus, for example, the variable values can be inserted by the FHS output server in interactive screen masks for convenience of use. (For further details, see also the “FHS” manual [19].)Re-use of output data as input data for later commands:
Data output by commands and stored in S variables can be used as input data for later commands. Not only can simple variables replace the values of individual operands in this way, but in the same way structure-type variables can replace operand structures, or even a complete command or statement.Selecting the output server at runtime:
The use of a dynamic selection mechanism for applications and S procedures means that the output server (e.g. SDF-P or FHS) does not need to be specified until runtime.Alternative usage of FHS
In the context of SDF-P, FHS is available as a server at both program and command level. Here, S procedures can be used to create applications for FHS.Redefinition of EXECUTE-CMD command jobs:
While ASSIGN-STREAM is used to create basic assignments, the EXECUTE-CMD command enables alternative assignments to be made for the default variable stream SYSVAR.Complementary or alternative outputs to SYSOUT and to S variables: S variables, or S variable streams, can be used as alternatives to the output to SYSOUT, or to complement it. The default setting for ASSIGN-STREAM is complementary output.
