Filename: LMARFC02.DOC Project: Template: MSGRIDA1.DOT Author: Mike Eddy Last Saved By: Launi Lockard Revision #: 24 Page: 35 of 15 Printed: 10/02/00 04:14 PM PAGE + Increments the section number and resets the page number to 1. Directives 35 POPCONTEXT context Restores part or all of the current context (saved by the PUSHCONTEXT directive). The context can be ASSUMES, RADIX, LISTING, CPU, or ALL. label PROC [[distance]] [[langtype]] [[visibility]] [[]] [[USES reglist]] [[, parameter [[:tag]]]]... statements label ENDP Marks start and end of a procedure block called label. The statements in the block can be called with the CALL instruction or INVOKE directive. label PROTO [[distance]] [[langtype]] [[, [[parameter]]:tag]]... Prototypes a function. PUBLIC [[langtype]] name [[, [[langtype]] name]]... Makes each variable, label, or absolute symbol specified as name available to all other modules in the program. PURGE macroname [[, macroname]]... Deletes the specified macros from memory. PUSHCONTEXT context Saves part or all of the current context: segment register assumes, radix value, listing and cref flags, or processor/coprocessor values. The context can be ASSUMES, RADIX, LISTING, CPU, or ALL. [[name]] QWORD initializer [[, initializer]]... Allocates and optionally initializes 8 bytes of storage for each initializer. Also can be used as a type specifier anywhere a type is legal. .RADIX expression Sets the default radix, in the range 2 to 16, to the value of expression. name REAL4 initializer [[, initializer]]... Allocates and optionally initializes a single-precision (4-byte) floating-point number for each initializer. name REAL8 initializer [[, initializer]]... Allocates and optionally initializes a double-precision (8-byte) floating-point number for each initializer. name REAL10 initializer [[, initializer]]... Allocates and optionally initializes a 10-byte floating-point number for each initializer.
36 Reference recordname RECORD fieldname:width [[= expression]] [[, fieldname:width [[= expression]]]]... Declares a record type consisting of the specified fields. The fieldname names the field, width specifies the number of bits, and expression gives its initial value. .REPEAT statements .UNTIL condition Generates code that repeats execution of the block of statements until condition becomes true. .UNTILCXZ, which becomes true when CX is zero, may be substituted for .UNTIL. The condition is optional with .UNTILCXZ. REPEAT expression statements ENDM Marks a block that is to be repeated expression times. Same as REPT. REPT See REPEAT. .SALL See .NOLISTMACRO. name SBYTE initializer [[, initializer]]... Allocates and optionally initializes a signed byte of storage for each initializer. Can also be used as a type specifier anywhere a type is legal. name SDWORD initializer [[, initializer]]... Allocates and optionally initializes a signed doubleword (4 bytes) of storage for each initializer. Also can be used as a type specifier anywhere a type is legal. name SEGMENT [[READONLY]] [[align]] [[combine]] [[use]] [['class']] statements name ENDS Defines a program segment called name having segment attributes align (BYTE, WORD, DWORD, PARA, PAGE), combine (PUBLIC, STACK, COMMON, MEMORY, AT address, PRIVATE), use (USE16, USE32, FLAT), and class. .SEQ Orders segments sequentially (the default order). .SFCOND See .NOLISTIF. name SIZESTR textitem Finds the size of a text item.
