Options File Information

The Options File Information record provides data about any option files passed to the assembler; using an external file (z/OS and CMS) with the DDname ASMAOPT or library member (z/VSE) with the name and type ASMAOPT.USER.

Field	Size	Description
Number of option (`ASMAOPT`) input files	FL4	The number of option files in this record. The groups of eleven option-file fields below occur n times depending on the value in this field.
Offset of option file	FL4	The offset from the beginning of this record to the first group of option-file fields. A value of binary zeros indicates that there are no option files.
		Start of option-file information groups, one group per file. The ellipses (...) indicate the fields are grouped.
...Offset of next option file	FL4	The offset from the beginning of this record to the next group of option-file fields. A value of binary zeros indicates that there are no more option files.
...Option file number	FL4	The assigned sequence number of the option file
...Option file name offset	FL4	The offset from the beginning of this record to the option file name
...Option file name length	FL4	The length of the option file name
...Volume serial number offset	FL4	The offset from the beginning of this record to the volume serial number
...Volume serial number length	FL4	The length of the volume serial number
...Member name offset	FL4	The offset from the beginning of this record to the member name. If no member name is applicable, this field contains binary zeros.
...Member name length	FL4	The length of the member name. If no member name is applicable, this field contains binary zeros.
...Option file name	CL(n)	The name of the option file for the assembly
...Volume serial number	CL(n)	The volume serial number of the (first) volume on which the option file resides
...Member name	CL(n)	Where applicable, the name of the member in the option file
		End of option-file information group.
Note: Where the number of option files exceeds the record size for the associated data file, the record is continued on the next record. The continuation flag is set in the common header section of the record. The current number of option files (for that record) is stored in the record and the record written to the associated data file. The next record contains the subsequent option files. The count of the number of option files is a count for the current record. Fields that have been written are not repeated in the next record. Fixed-length fields are initialized to binary zeros or spaces, and variable-length fields have a length of binary zeros.
