ADDWORD – Add words to a list
This function adds one or more words to a list, if they are not already existing in the list.
ADDWORD(<list>,<new-items>)
Where:
<list>
- The current list of words.
<new-items>
- The new words to be added to the list, separated by blanks.
For each word defined in <new-items>
, a check is performed to see if
it already exists with the same format in the <list>
. The function
returns the original list, with any<new-items>
not already contained
within it appended to the list.
For example:
VARSUB SCAN
VARSET IR = "SCOTT VIRGIL ALAN GORDON JOHN"
VARSET IR = ADDWORD("!IR","BRAINS TIN TIN") variable IR set to
GORDON JOHN BRAINS "SCOTT VIRGIL ALAN TIN"
VARSET VARSET IR = IR = ADDWORD("!IR","ALAN GEOFF") variable IR set to
"SCOTT VIRGIL ALAN GORDON JOHN BRAINS TIN GEOFF”
