Description
Adds comments to macros or scripts. Comments are treated like any other unknown commands and are ignored by the PTC ALD processor.
Example 189. Sample comments in a script
PTC ALD scripts are perhaps one of the most useful areas in which comments can be used since they can be difficult to follow if you are not the author. The example below illustrates a few lines of script with comments for each line:
`set the variable ^num_found to the value of the number
found from the last search
getvar 21526,"num_found"
`test if the ^num_found variable has a value of zero and
if so, jump to the exit label
?=^(^num_found),^(0) }exit
Example 190. Add a comment without it being included in the text stream
Comments are a useful way of keeping track of any key assignments you make using the * macro. If the macro preceding a comment is @ (insert), you should enclose that @ macro in parentheses to avoid the comment being inserted in the text stream:
*1023 (@&I;) 'Call to italic .rf tag
