record variable : field name
You can use :
(colon) to select an individual field of a record:
declare record metadata-label field string author field string title field string publisher field integer year field switch in-print initial {true} process local metadata-label doc-info set doc-info:author to "Mark Baker" set doc-info:title to "Internet Programming with OmniMark" set doc-info:publisher to "Kluwer Academic Publishers" set doc-info:year to 2000 set author-name to doc-info:author output doc-info:title
The field selection operator can also be used to select a field from an expression of a record type. The expression must be parenthesized. Thus, the field selection operator can be applied to a function call if that function returns a record type:
declare record point field integer x field integer y declare record pixel extends point field stream color define dynamic point function move-point value point a to value point b as local point c set c:x to b:x set c:y to b:y return c define overriding point function move-point value pixel a to value point b as local pixel c set c:x to b:x set c:y to b:y return c process local point a variable local pixel b local point c set b:x to 5 set b:y to 78 set b:color to "red" set c:x to 87 set c:y to 56 output "d" % (move-point b to c):x
