Keywords

Any BPXWDYN keyword that accepts a variable name for returned information allows for a file descriptor number. For example, inrtpath(1) writes the path name, if available, as a line to descriptor 1. Additionally, when BPXWDYN is used from languages other than REXX and variables are not available, information can be returned by means of the parameter list as described in Conventional MVS parameter list.

The ordering of keywords on the request is arbitrary. You cannot specify the same keys multiple times for one request.

BPXWDYN does not perform consistency checking on keys. If some keys are not valid when combined together on a single request, dynamic allocation or dynamic output fails the request.

Some keywords accept arguments within the following guidelines:

Keyword arguments must be specified within parentheses. Spaces are not permitted between the key and the opening parenthesis, or anywhere within the additional argument string through the closing parenthesis, unless the argument string is quoted. Spaces are permitted between key specifications. Where multiple arguments are permitted, the arguments must be separated by commas.
An argument can be enclosed within single (') or double (") quotes. Two adjacent quotes cannot be used to represent a single quote within a quoted string.
Arguments that are not quoted are treated as uppercase. Arguments that are quoted are only treated as mixed case if it makes sense for the keyword.
Arguments that accept REXX variable names are accepted when BPXWDYN is called from any environment, but are only effective when called from a REXX environment.
