CNV BIN

Expected Behaviour

o UNICODE Alpha Field from Numeric field or NATIONAL Alpha Field from Numeric Field

• Converts the value of the specified Numeric Field to a 4-byte unsigned binary integer and stores it in the 1- character (4-byte) Unicode/National Alpha field.
• The UNICODE/NATIONAL Alpha Field must be defined as a 1 character (4-byte internal length) field.
• Em build should fail if the character length of the UNICODE/NATIONAL Alpha Field is greater than 1 character.
• An Overflow error should occur at runtime if the value of the Numeric Field is greater than the maximum value that can be stored in a 4-byte unsigned binary integer.
• An Overflow error should occur at runtime if the value of the Numeric Field is negative.

o UNICODE Alpha Field from Literal Value or NATIONAL Alpha Field from Literal Value

• Converts a numeric literal value to a 4-byte unsigned binary integer and stores it in the 1- character (4-byte) UNICODE/NATIONAL Alpha field.
• The UNICODE/NATIONAL Alpha Field must be defined as a 1 character (4-byte internal length) field.
• The numeric literal value must be a positive decimal value.
• Em build should fail if the numeric literal value is negative.
• Em build should fail if the character length of the UNICODE/NATIONAL Alpha Field is greater than 1 character.
• An Overflow error should occur at runtime if the value of the Numeric Literal is greater than the maximum value that can be stored in a 4-byte unsigned binary integer. (Maybe this should be an Em build error instead)

o UNICODE Alpha Field to Numeric Field or NATIONAL Alpha Field to Numeric Field

• Converts a 4-byte unsigned binary integer value that is stored in a 1-character (4-byte internal length) UNICODE/NATIONAL Alpha Field to an equivalent value stored in the specified Numeric Field.
• The UNICODE/NATIONAL Alpha Field must be defined as a 1 character (4-byte internal length) field.
• Em build should fail if the character length of the UNICODE/NATIONAL Alpha Field is greater than 1 character.
• An Overflow error should occur at runtime if the value of the 4-byte unsigned binary integer is greater than the maximum value that can be stored in the specified Numeric Field.

Test Plan

• convert valid numeric field unicode value to alpha/national and alpha/unicode
• try to CNV BIN from numeric field into alpha/national and alpha/unicode that are not 1 character (Em build error)
• try to CNV BIN from numeric field into alpha/national and alpha/unicode from invalid numerics (negative, >=4294967296)
• convert valid literal unicode value to alpha/national and alpha/unicode
• try to CNV BIN from literal into alpha/national and alpha/unicode that are not 1 character (Em build error)
• try to CNV BIN from literal into alpha/national and alpha/unicode from invalid numerics (negative, >=4294967296)

BUGS

• Painted 1 character alpha/national field on image, displayed as 4 characters. alpha/unicode was ok
• CNV BIN from negative literal does not generate compile time error, generates 'Invalid Sign' runtime error. Might not be actual bug, just different implementation?
