The following example uses two instances of the PAUSE verb to request responses
from the operator. The procedure tests the initial response, and if it is “GO YES,” a
further response is requested. This last response is split into variables &20 through
&22:
PAUSEX:PROCEDURE
WRITE DATA="ENTER ""GO YES"" TO CONTINUE, ""GO NO"" TO END".
LABEX:
PAUSE ARGS
IF &1 = NO THEN EXIT
IF &1 = YES THEN GOTO LAB1
ELSE SAY "AN ERROR HAS OCCURRED - TYPE
""GO YES"" OR ""GO NO"""
GOTO LABEX
LAB1:
PAUSE ARGS RANGE=(20,22),
DATA="PAUSED AGAIN. ENTER "GO" ONCE MORE"
EXIT
END PAUSEX
The following example reads the operator response text and splits the message into
individual words:
PAUSE VARS=(*(3),&A(2),&B(3),&C,&D,&E,&F)
In the previous example, the first three words are ignored, two characters of the next
word are placed in the variable &A, and three characters of the next word are placed
in the variable &B. The next four words are placed in the variables &C, &D, &E, and
&F. Any remaining characters in the string are not available.
The following example waits for the next log message, then splits it and places the text
into a series of automatically generated variables of the form ABC1, ABC2, and so on.
As many variables as required are generated, to the limit specified by the RANGE
operand-in this case, from 1 through 50:
PAUSE VARS=&ABC* RANGE=(1,50)
