PREPRM, PREPRO, PREPF$, and POSTPR$ PREPRM dynamically attaches internal filenames to the filenames specified in the first two fields as follows: SI$$ is attached to field-1 and SO$$ is attached to field-2. field-1 (SI) is expected to contain the symbolic input to the processor. PREPRM checks that the element specified is typed as symbolic (element type 01). field-2 (SO) is typically used for the updated symbolic output element if corrections have been applied to the input symbolic element in field-1 (SI). This would apply if the routine SIR$ will be used. However, field-2 (SO) may be used for other types of output elements. The mnemonics SI, RO, and SO appear in error messages output by PREPRO and PREPRM. They refer to the first three fields on the processor call statement as follows: SI field-1 RO field-2 SO field-2 if PREPRM is used; field-3 if PREPRO is used 14.1.1. PREPRO–Preprocessor Routine PREPRO reads the processor call statement in internal format (INFOR) (see Section 12), standardizes its form in PARTBL (see Figure 14-1), and dynamically assigns the necessary files. PREPRO obtains the “next write location” for program files and, for tape files, verifies that the source input element exists. Initial Conditions The processor must call PREPRO before it executes any read command such as ER SYMB$ (READ$ function), ER AREAD$, or ER READ$. The parameter table PARTBL must be externally defined and at least 40 words long. It also should be zero-filled. Calling Sequence LMJ X11,PREPRO$ error return normal return Error Return The error return is taken under the following conditions: I/O error occurs (A0 = 0) error when reading INFOR (A0 ≠ 0) tape positioned improperly (A0 ≠ 0) file does not exist (A0 ≠ 0) file is not a program file (A0 ≠ 0) 14–2 7833 1733–004
PREPRM, PREPRO, PREPF$, and POSTPR$ The PARTBL that the calling program provides is filled with the data that is necessary to process the files. The input/output files are assigned as follows: SI assigned RO assigned exclusively SO assigned exclusively If SI is the same file as RO or SO, it is assigned exclusively. 14.1.2. PREPRM–Preprocessor Routine PREPRM generates the source input and source output fields of PARTBL (see Figure 14-1). It performs dynamic assigns and program file searches on the source input and source output files. Initial Condition PARTBL must be externally defined and 27 words long (or 40 words long if relocatable output field is needed). It should be zero-filled. Calling Sequence LMJ X11,PREPRM$ error return normal return The information on the processor call statement is transferred to PARTBL (see Figure 14–1). The input/output files are assigned as follows: Symbolic input assigned Symbolic output assigned exclusively If the symbolic input file is the same file as the symbolic output file, the symbolic input file is assigned exclusively. On error return, an error message is printed. The PREPRO and PREPRM automatically fill PARTBL fields when called. The fields are filled with data needed by the SIR$, ROR, SOR, and POSTPR$ routines of <strong>SYSLIB</strong>. 7833 1733–004 14–3
