The SPACE command in SYSVIEW was returning byte totals in Decimal format instead of Binary format.
The SPACE display Option is set to DECEDIT. That will cause the storage byte counts to be decimal (base-10).
To change to binary (base-2), in the SPACE display, put the cursor on the DECEDIT Option and hit enter. That will change the option to HEXEDIT and the storage statistics for FByt, LByt, and TByt to binary.
Adding the following to a batch SPACE command string will change the output from decimal to binary:
Adding the same continuation (;OPT HEX) will work, as long as the command string is enclosed in single quotes.
