IDENTIFICATION DIVISION.
PROGRAM-ID . ACCNUM.
AUTHOR. D. VISSER.
DATE-WRITTEN. 05-May-83.
DATE-COMPILED.
************************************************************************
*****
***** PROGRAM NAME: ACCNUM
*****
***** PURPOSE:
***** Transfer and validate the, assumed numeric, input
***** ( which will be alfanumeric, left justified ) into
***** a numeric field, right justified.
*****
***** NOTES:
***** VAX-11 COBOL accepts as alfanumeric-fields,
***** left-justified, regardless of the picture specified
***** for the receiving field ( accept actually overwrites
***** this picture). No error will occur displaying
***** the receiving field ( which is now alfanumeric ),
***** but invalid data is transfered when moved into
***** another numeric- or numeric-edited field.
*****
***** Parameters to be passed on to this subroutine and will
***** be handed back are (in this order to be passed on) :
*****
***** WK-ALFANUMERIC : 18 characters alfanumeric, containing
***** the input to be transfered.
***** WK-NUMERIC : 13 digits and 5 decimals numeric,
***** containing the return value.
***** WK-ERRORFLAG : 1 character alfanumeric containing
***** the return-status (error-indicator).
***** This field can contain :
*****
***** " " : successfull transfer.
***** "1" : too many delimeters specified.
***** "2" : use either ',' or '.', not both.
***** "3" : input is non-numeric.
***** "4" : too many digits ( max. is 13 ).
***** "5" : to many decimals ( max. is 5 ).
*****
***** This routine will validate the accepted (alfa-
***** numeric) field 'WK-ALFANUMERIC', respect decimal-input
***** and/or negative values, reformat the input-string to
***** a numeric-field 'WK-NUMERIC', which is linked back to
***** the program. In case an error is encountered in the
***** process, the error-indicator, 'WK-ERRORFLAG', will be
***** set to the right value. If no error occurs, this field
***** will contain a space.
***** No messages are displayed in this sub-routine, but the
***** calling program can inspect the 'WK-ERRORFLAG'-setting
***** to generate the right message ( if wanted ).
