AS(1) (PDP11) AS(1) NAME as - assembler SYNOPSIS as [ - ] [ -o objfile ] file ... DESCRIPTION As assembles the concatenation of the named files. If the optional first argument - is used, all undefined symbols in the assembly are treated as global. The output of the assembly is left on the file objfile; if that is omitted, a.out is used. It is executable if no errors occurred during the assembly, and if there were no unresolved external references. FILES /lib/as2 pass 2 of the assembler /tmp/atm[1-3]? temporary a.out object SEE ALSO ld(1), nm(1), adb(1), a.out(5) UNIX Assembler Manual by D. M. Ritchie DIAGNOSTICS When an input file cannot be read, its name followed by a question mark is typed and assembly ceases. When syntactic or semantic errors occur, a single-character diagnostic is typed out together with the line number and the file name in which it occurred. Errors in pass 1 cause cancellation of pass 2. The possible errors are: ) Parentheses error ] Parentheses error < String not terminated properly * Indirection used illegally a Error in address b Branch instruction is odd or too remote e Error in expression f Error in local (`f' or `b') type symbol g Garbage (unknown) character i End of file inside an if m Multiply defined symbol as label o Word quantity assembled at odd address p `.' different in pass 1 and 2 r Relocation error u Undefined symbol x Syntax error AS(1) (PDP11) AS(1) BUGS Syntax errors can cause incorrect line numbers in following diagnostics.
