C Abstract
|
|
C XSETF sets the error control flag value to KONTRL.
|
|
C (KONTRL is an input parameter only.)
|
|
C The following table shows how each message is treated,
|
|
C depending on the values of KONTRL and LEVEL. (See XERMSG
|
|
C for description of LEVEL.)
|
|
C
|
|
C If KONTRL is zero or negative, no information other than the
|
|
C message itself (including numeric values, if any) will be
|
|
C printed. If KONTRL is positive, introductory messages,
|
|
C trace-backs, etc., will be printed in addition to the message.
