SQL iQuery Script Built-in Function

Index

ToHex

Convert data to 2-hexadecimal characters using the CVTHC MI instruction.

The TOHEX() built-in function returns 2 hexadecimal characters the represent each single character of parameter 1.

Syntax

The ISHEX() passes the first parameter to the cvthc MI instruction. That instruction "unfolds" the characters; creating 2 hexadecimal bytes for each single byte of parameter 1. For example, the string '38' is translated to 'F3F8'.

Parameters

  1. The name of an iQuery Session Variable to be converted to hexadecimal.
SELECT SUBSTR(data,21,5) INTO &AMTDUE
FROM CUSTMAST
WHERE CUSTNO = 12;

eval &CustData = toHex(&amtDue);
if (&custData = '4040404040');
#msg This customer has a decimal data error (blanks) in the Amount Due column
else;
// continue normally
endif;

The legacy file CUSTMAST has some "program described" data. We extract positions 21 to 26 which should have the amount due as a packed field. If it is all banks (x40) a message is sent and the request ends. Otherwise it continues normally.
