IDENTIFICATIO N: Resume translation of DEC directive (TENC)

PURPOSE: To initialize parameters and exit location when resuming the translation of the operand field of a DEC directive which expands to more than 72

characters.

ACTION:

PROGRAMMI NG CONVENTIONS:

CALLING SEQUENCE:

MEMORY

REQUIREMENTS:

SUBROUTINES USED:

TENC sets S4B to the location of the EXU EMPTY instruction plus 4 and then calls RESET to initialize the card buffer for resuming the translation. TENC exits to TEN3 to continue the translation process.

TENC is executed only after the DEC translation code is unable to translate the input image into a 72-character META-SYMBOL equivalent because of space. It assumes the ENCODER wi II remotely execute the instruction at EMPTY. TENC is a relocatable routine assembled as part of S4B.

A BRM TENC is stored in EMPTY, and TENC is called when EMPTY is executed.

IDENTIFICATION: Resume translation of OCT directive (OCTC)

PURPOSE: To reset the S4B exit and the symbolic input buffer to resume the translation of the OCT directive.

ACTION: aCTC sets S4B to the location of the EXU EMPTY plus 4 and then calls RESET to initialize the symbolic input buffer to resume translation of the OCT directive.

PROGRAMMING TECHNIQUES:

REQUIREMENTS:

SUBROUTINES USED:

OCTe is called only when during the translation of an OCT directive the symbolic card buffer filled before the translation could be completed. It assumes the ENCODER will remotely execute cell EMPTY. OCTC is a relocatable routine assembled as part of S4B.

A BRM OCTC is stored in EMPTY during the translation of an input OCT directive. OCTC is called by executing EMPTY remotely.

ACTION:

PROGRAMMING TECH NIQUES:

CALLING SEQUENCE:

REQUIREMENTS:

SUBROUTINES USED:

NAME sets the exit from S4B and calls RESET to initialize the symbolic input buffer. NAME then sets NAME in the operation field of the buffer and the label from the MACRO line into the label field in the buffer. Before exiting S4B, NAME sets EMPTY to contain BRM PARAMS for translating the parameters to the MACRO sample.

NAME is called only as a result of encountering an input MACRO line.

NAME is a relocatable routine assembled as part of S4B.

BRM NAME is stored in EMPTY

NAME is called when EMPTY is executed.

NAME returns to the EXU EMPTY plus 4.

for the parameter. PARAMS sets the S4B exit location and then calls RESET to initialize the input buffer. The next parameter is then placed in the label fierd, the operation is set to EQU, and the operand field is set to the REFLIST (n), where REFLIST is the label given the PROC line generated in place of the MACRO and n is the current parameter number.

PARAMS is called only after generating a NAME line as part of the trans-lation of a MACRO. PARAMS is a relocatable routine assembled as part of S4B.

PARAMS is called by an EXU EMPTY after EMPTY has been set with a BRM PARAMS by the NAME routine. Return is to the EXU EMPTY plus 4.

Catalog No. 042016 IDENTIFICATION: Initialize I/O control cells and copy symbolic corrections (MON1)

PURPOSE: To initialize the file maintenance and I/O device handling control words of MSCONTRL, to copy symbolic corrections to scratch tape X2 if needed, and to set the delay loop timing for paper tape reading.

ACTION: MONl examines each entry of the unit assignment table (UAT) referenced by the assembly system and each entry in the MSFNC control word to deter-mine which I/O functions and devices are to be used for the run. If a func-tion is requested, MONl inserts an entry into a control cell of the following format:

C is channel designation U is unit number

A is address of routine to perform function

The above control words are found in MSCONTRL from MONBO through MONLF. In addition, the control flags USI through USO in MSCONTRL are set by MON 1 in the following format:
