PARAM Command
•
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).
For more information on the PARAM command, see the TACL Reference Manual.
