SIR$–Symbolic Input/Output Routine
If input is from an element, the SDF type is tested. If S3 of the label control record is
nonzero and not the Fieldata character "S", the message 'SI IS NOT SIR TYPE' is printed.
All cycling information in the control words is then ignored.

Returns
OPNSR$ takes the error return if:
• SDFI is unable to open the symbolic input. Register A5 contains the I/O error status
code from SDFI.
• An attempt is made to process an invalid SDF file or element. Register A5 is set to
zero. The associated error message is
INVALID SDF LABEL WORD w
where w is the first two words of the element or file printed in Fieldata.
23.2.2. INISR$–Initialize SIR$ Input and Output
INISR$ initializes SIR$ to allow input and output of symbolic data. INISR$ performs the
first or second pass initialization functions described for OPNSR$ and additionally allows
the calling program to control certain SIR$ actions.
Calling Sequence
L A4,initialization-word
LMJ X11,INISR$
error return
normal return
The initialization-word is provided by the caller to control certain SIR$ actions.
The initialization-word can contain
• A list of specific SDF control record types that SIR$ should not pass to the calling
program.
• A flag to indicate that SIR$ should not create source output if certain conditions are
met.
• A flag to indicate that when an ASCII-like image is passed to the calling program,
SIR$ should include the CCS for the image.
• A flag to indicate that SIR$ should pass images in all 63 legal CCSs to the calling
program and should include the CCS for the image.
