B.2.3 Data Type Differences

• For floating point and integer COMP-5 data (32-bits or less), the PRECISION, LENGTH and SCALE values under 5.0 were "0". Under 5.1, these values are derived from the size of the data.

• For all integer numeric types, the LENGTH field is different in Version 5.0 than in Version 5.1. This field is the buffer size needed to hold a return value from a "get data" call. The 5.1 values are always greater than or equal to the actual size needed. The 5.0 values are one too small for signed data.

• The returned data format is different for some numeric forms. The logical value is the same; just the format is different. For example, Version 5.0 returns a PIC 9(4) VALUE ZERO field as "+0000" while Version 5.1 returns the same field as "0".
