There can be spaces between the variable specification and the opening parenthesis.
You cannot follow the variable specification with an asterisk (*) when you follow it by
(
length
).
The value of length can be a constant or an expression. Constants must be integers in
the range 1 through 32000. Expressions must resolve to integers in this range.
Here are some examples. (These examples assume PARSE=YES.)
What You Type Meaning
INTREAD VARS
(&A(10),&B(20),&C(30),&D,&E,&F)
Places 10 bytes of the first word read in &A,
20 bytes of the second in &B, 30 bytes of the
third in &C, and the next three words in &D,
&E, and &F respectively.
PAUSE VARS=(&NAME(15)) Places 15 bytes in &NAME, truncating it if
necessary.
Skipping Words If you are using a VARS list in a verb that reads a message, such as EMSREAD,
INTREAD, LOGREAD, or MSGREAD, and the PARSE=YES option is used, you can
use the skip option of the VARS list to skip a number of words.
skip
specifies the
number of words that are not to be stored into variables at this point. This VARS list
option is useful when assigning a sequence of words into variables, and some words
are not required. Here is the component of the VARS list that you use to skip a
number of words:
* [ (
skip
) ]
The value of
skip
can be a constant or an expression. If constant, it must be an integer
in the range 1 through 32000. If an expression, it must resolve to an integer in this
range.
An asterisk by itself is the same as *(1). Here are some examples:
What You Type Meaning
INTREAD
VARS=(*(3),&A(10),*(1),&B(20))
Skips the first three words, places
10 bytes of the fourth word read in
&A, skips the next word, and
places 20 bytes of the sixth word in
&B.
MSGREAD
VARS=(&NAME,*(2),&ADDRESS(20),*,&AGE)
Places the first word in &NAME,
skips the next two words, places 20
bytes of the fourth word in
&ADDRESS, skips the fifth word,
and places the sixth word in &AGE.
