[fitsbits] Start of the CONTINUE keyword Public Comment Period
Peter Teuben wrote:
perhaps it would be useful to explicitly mention that the & character is not part of the resulting keyword value. And also make the example shorter so you can easily show the equivalent string in a single-keyword example: Agreed. I'll make these changes in the next version of the documentation. Thomas McGlynn wrote: It might be useful to explicitly address some corner cases, e.g., long strings that end in &. SVALUE = 'This is a long string &' CONTINUE 'really long &' COMMENT 'But is this part of it?' CONTINUE 'Or is this?' I guess that the intended value of SVALUE in this case is 'This is a long string really long &' Correct. If a string value ends with an `&' and is NOT followed by a CONTINUE keyword, then the `&' character is interpreted literally as the last character of the string value). You might also wish to explicitly note what is supposed to be done with a CONTINUE statement that doesn't follow a string ending in &. Presumably it is to be ignored. SVALUE = 'This is a short string' CONTINUE 'And this is not part of it' Yes. Software should treat orphaned CONTINUE keywords the same as a COMMENT keyword. Software that doesn't support this convention at all should treat all the CONTINUE keywords this way. I'll revise the documentation to explicitly cover these cases.
