Metacharacters & pattern matching

[Ken Langendock]

Have you checked the PDL for your dictionary and made sure that symbol is not used as a “Reserved” or any other option in the “System Options” declaration of the PDL?

 

This might cause some weird issues.

Let’s see if anyone else can crack this, because I am fed up seeing the message “Invalid pattern specification.  Check pattern syntax.”

 

Operating system is VMS v7.2-2,

PowerHouse version 7.10.E6 (as it has been for rather a long time…).

 

I have an element which has an existing pattern of “(\!|)*”. This allows any number of any alphanumeric character with the exclusion of the “post” character, as we use this as a delimiter for some data imports into Excel.

 

Last week we had an interface fail as the result of the inclusion of a £ character in the data. I have tried to amend the pattern to something along the lines of “(\((!|)|£))*”, but this gives the error message above. The current try has "(\£|(!|))*", but any input into this triggers the message “There is a control character in this pattern.”

 

Any suggestions? So far as I am aware, all the entries on the metacharacter screen are defaults.

 

Thanks,
