SYS_LAST_ERR_INS

Script Function: Supplies the variable message part of the last error

Syntax

SYS_LAST_ERR_INS()

Return codes
Variable message part of the last error " " - No error has occurred

Comments

Some script elements facilitate continued script processing in the case of occurring errors when :ON_ERROR is used. The script function then retrieves the variable part of the error message .

Most error messages do not only consist of a pre-determined text. Parts of the message refer to object names or script lines, for example. These variable parts of error messages are put in inverted commas.

Example of an error message:

U0020645 - Runtime error in object '&01', line '&02'.: There is no object '&04'.

The variable parts are replaced by values when the above error message is output:

U0020645 - Runtime error in object 'MOVE_OBJECT', line '0003'. There is no object 'MM.CLOSING.2005'.

Example

The example shown below intends to check a hard drive's memory. An error occurs if this hard drive is not available or cannot be accessed. The corresponding error number and variable message parts are read and the entire AE error message is retrieved and sent to a user.

:SET &CHECK# = GET_FILESYSTEM("WIN21G", "Z:\", FILESYSTEM_SPACE_TOTAL)
:SET &ERRINS# = SYS_LAST_ERR_INS()
:IF &ERRINS# NE ""
:   SET &ERRNR#   = SYS_LAST_ERR_NR()
:   SET &MESSAGE# = GET_MSG_TXT (&ERRNR#,&ERRINS#)
:   SEND_MSG BU,BU,&MESSAGE#
:ENDIF
