<buttons> integer would be 18.

Ok
Ok & Cancel
Yes & No
Yes, No & Cancel
Retry & Cancel
Abort, Retry & Ignore

MSTR
Syntax: MSTR <variable> <string> <start> [<end>]
This command will copy a number of characters from within a string and place them
in a variable, where
<variable> is a predefined string variable (see var) which will store the copied
characters.
<string> is the source string from which characters are to be copied.
<start> is the numeric position of the first character to be copied, where the
first character in the source string is 1. This value must be a number
greater than 0.
<end> is the numeric position of the last character to be copied, where the first
character in the source string is 1. If this is omitted then all the charac-
ters to the end of the string will be copied. If this value is greater than
the number of characters in the source string then the destination
variable will include padded spaces so that it matches the number of
characters requested. If this value is less than the <start> value then it
will result in an empty string.
