| X2B
Output: UPPER('cexpr') or (UPPER 'cexpr') converts the alphabetic
characters a-z in the argument to upper case, A-Z. Null arguments return a
null string.
Examples
UPPER('aBcDefG')
| Format: Function-invocation
| Operands: Character
has value 'ABCDEFG'
| Output: X2B('hexstring') converts the value of its argument string of
| hexadecimal characters to a character string containing only zero ('') and
| one ('1') characters representing the same bit pattern. Null arguments return
| a null string.
| If the result is not too long, the length of the result is four times the length of
| the 'hexstring' argument.
| The operand must contain only hexadecimal digits. Any other value causes
| the message ASMA214E to be generated.
| Examples
| X2B('') has value '' (null string)
| X2B('') has value ''
| X2B('1') has value '1'
| X2B('F3') has value '111111'
| X2B('F3') has value '111111'
| X2C
| Format: Function-invocation
| Operands: Character
| Output: X2C('hexstring') converts the hexstring argument to characters
| representing the same bit pattern. Null arguments return a null string.
| If needed, the argument string is padded internally on the left with a zero
| character so that its length is a multiple of two.
| The operand must contain only hexadecimal digits. Any other value causes
| the message ASMA214E to be generated.
| Examples
| X2C('') has value '' (null string)
| X2C('F3') has value '3'
| X2C('') has value 'n' (EBCDIC null character)
| X2C('F1F2F3F4F5') has value '12345'
| X2C('F1') has value 'nn1'
| X2D
| Format: Function-invocation
| Operands: Character
| Output: X2D('hexstring') converts its argument string of at most eight
| hexadecimal characters to one to ten decimal characters preceded by a plus
| or minus sign, representing the value of the argument. Null arguments return
| '+'. For example:
