_dstestlib

Test the prior existence of test dataset in WORK or test data directory.

%_dstestlib(dsn, _lib_=);

Argument

dsn : name of the test dataset; it is in general of the form: "_dstestXX" where XX defines the number of the test; in practice, dsn is passed to this macro from the calling macro using &sysmacroname.

Returns

_lib_ : in the macro variable whose name is passed to _lib_, the library (location) of the dataset dsn whenever it already exists; it is either WORK or the default test data library (e.g., &G_PING_TESTDB).

Note

This macro is not used 'as is', but it is generically called by all datatest macros of the form `"_dstestXX".
