In this report authors relate of VALSAS IV, Assembler for FACOM-231. The representative characteristics of it are One Pass system and Utility subroutines built into it. One Pass system : When the source program passes through the tape-reader one time, it is translated into the object program at once. The mean processing time is 0.5 second per one step. Utility subroutines are divided into two kinds as follows : 1. Standard functions SQRT : 221/SQRT, A, B. SIN : 221/SIN, A, B. COS : 221/COS, A, B. EXP : 221/EXP, A, B. LOG : 221/LOG, A, B. ANGTG : 221/ANGTG, A, B. ABS : 221/ABS, A, B. For example 221/SQRT, A, B. <221> is Link Order. A and B are location symbols which indicate the least significant digits of fields. When this order is executed, the value of square root of <A> is stored in B field. 2. I/O subroutines READINTEGER : 221/READINTEGER, I. READREAL : 221/READREAL, A. PRNTINTEGER : 221/ PRNTINTEGER, I. PRNT : 221/PRNT, A. PRNTREAL : 221/ PRNTREAL, A, i. PRNTFIX : 221/PRNTFIX, A, i, j. PRNTX : 221/PRNTX : 221/PRNTX, I, i. PRNTSTRING : 221/PRNTSTRING, LS. SPACE : 221/SPACE, i. CRLF : 221/CRLF, i. These orders read in, print numerics or characters with various types.
