• Additional Considerations
A parameter value that contains any embedded commas or leading or trailing spaces
must be enclosed in quotation marks. Between the delimiting quotation marks, two
◦
consecutive quotation marks ("") represent any one quotation mark (") that is part of the
value. The delimiting quotation marks are not stored.
◦ TACL provides internal storage for 1024 bytes of parameters. Each parameter occupies
a number of bytes equal to:
2 +
number-of-characters-in-parameter-name +
number-of-characters-in-parameter-value
◦ Multiple PARAM name and value pairs must be delimited by commas.
◦ The compiler makes use of certain parameters and their values in performing the
compilation (see PARAM Commands (page 527)).
For more information on the PARAM command, see the TACL Reference Manual.
