StorageTek 6 manual Control Statement Syntax Conventions

Control Statement Syntax Conventions

The control statement for each utility program consists of a command (indicating the utility function) followed by parameters, as applicable, in 80-character card-image records. The standard syntax conventions for control statements are as follows:

•The only valid control statement information area is from column 2 to column 72. Columns 73-80 are ignored.

•Parameters are separated by one or more blanks or a comma.

•A value is associated with a parameter by an equal sign (=) or by enclosing the value in parentheses, and concatenating it immediately after the parameter. # Case (upper or lower) is ignored in actual control statements.

•Control statements may be interspersed with comments designated by an asterisk (*) in column one.

For definition data sets (VOLATTRs, UNITATTRs and TAPEREQs) comments must be in the new format (/*...*/). Asterisk (*) comments are not allowed. A /*...*/ comment in the first line is not required for definition data sets.

•A control statement is terminated if the statement is not continued. Control statements must have a /*...*/ comment as the first control statement in the PARMLIB member. A PARMLIB member that does not begin with a /*...*/ style comment is assumed to be in the old format. Comments in old format members must begin with an asterisk in column 1.

In contrast to utility control statements, PARMLIB control statements may begin in column 1. Columns 73-80 are ignored.

To allow for continuation, comments in the job stream must start with /* and end with */. Comments cannot be nested, and mixing the two comment styles (* and /*) is not allowed.

•The 80-character card-image records use conventional continuation rules.

-A space and a dash (–) following a parameter or parameter value indicates that a blank is to be inserted between the last nonblank character of this line and the first nonblank character of the next nonblank record.

-A plus sign (+) specifies that the continued control information is to be concatenated directly after the character preceding the plus sign. The continued data starts at column two of the next nonblank record.

Note: You can use a continuation only after a new keyword or after the natural end of a value. Some examples follow.
