Specifies the first line of the generated DD statement for the site-specific template library concatenation, as specified on the TMPDDLN keyword. tm_line1 can be up to 54 characters in length, and must conform to standard job control conventions. If your JCL statement includes one or more commas, then enclose the whole statement within single quotation marks. The data set so referenced must exist.

You can specify a value for STMJCL1 even if you have not specified a value for TMPDDLN. However, if you have specified a value for TMPDDLN, then also specify a value for STMJCL1.

For an example, see Examples of HFM2SSDM macros.
