Example 1: The following 2 validation blocks are functionally identical.
The first uses a "standard" validation check:
BEGINCHECK
CONDCHECK FIELD(#QUANTITY) COND('(#QUANTITY >= 0) AND (#QUANTITY <= (#MEASURE * 1.462))') MSGTXT('Quantity exceeds top measurement factor or is negative')
ENDCHECK
The second uses the SET_ERROR command to achieve exactly the same result:
BEGINCHECK
IF COND('(#QUANTITY < 0) OR (#QUANTITY > (#MEASURE * 1.462))')
SET_ERROR FOR_FIELD(#QUANTITY) MSGTXT('Quantity exceeds top measurement factor or is negative')
ENDIF
ENDCHECK
Example 2: The following 2 validation blocks are also functionally identical.
BEGINCHECK
FILECHECK FIELD(#PRODNO) USING_FILE(PRODUCT) MSGTXT('Product number not found in product master')
RANGECHECK FIELD(#ORDNUM) RANGE(A000000 Z999999) MSGTXT('Order number is not in range A000000 to Z999999')
RANGECHECK FIELD(#QUANTITY) RANGE(1 9999) MSGTXT('Quantity ordered must be in range 1 - 9999')
ENDCHECK
and
BEGINCHECK
CHECK_FOR IN_FILE(PRODUCT) WITH_KEY(#PRODNO)
IF_STATUS IS_NOT(*EQUALKEY)
SET_ERROR FOR_FIELD(#PRODNO) MSGTXT('Product number not found in product master')
ENDIF
IF '(#ORDNUM < A000000) OR (#ORDNUM > Z999999)'
SET_ERROR FOR_FIELD(#ORDNUM) MSGTXT('Order number is not in range A000000 - Z999999')
ENDIF
IF '(#QUANTITY < 1) OR (#QUANTITY > 9999)'
SET_ERROR FOR_FIELD(#QUANTITY) MSGTXT('Quantity ordered must be in range 1 - 9999')
ENDIF
ENDCHECK
