GETPSF$–Get a Scratch File Routine 10.2. MASM Interface The next two subsections describe the packet and the calling sequence. 10.2.1. Packet On a call to the relocatable version of the GETPSF$ routine, the calling program passes the number of files or the specific PSF file number to be assigned to the run. For a call to the common bank version of the routine, the calling program must also provide the address of a 13-word data area that is used by the GETPSF$ routine. This is a scratch data area that does not have to be initialized by the caller and can be reused by the calling program when control returns from GETPSF$. The packet must be in a writeenabled bank of the calling program. The bank must also be based when the call to the GETPSF$ routine is made. For more information on the different methods of calling the <strong>SYSLIB</strong> routines, see Section 3. 10.2.2. Calling Sequence The GETPSF$ routine is called by the MASM procedure G$ETPSF. This procedure can be used to generate the calling sequence for the relocatable version, the common bank version, or the common bank version using the Auto Switch calling sequence. Calling Format G$ETPSF[,t] func-code [,n] [pkt-addr] error return normal return Parameters t Call the relocatable version. This parameter is optional and may be omitted. CB or A, if specified, must be enclosed by apostrophes. blank Call the relocatable version. This is the default if t is omitted. 'CB' Call the common bank version. 'A' Call the common bank version using the Auto Switch method. 10–2 7833 1733–004
func-code GETPSF$–Get a Scratch File Routine The function code tells GETPSF$ how to treat the parameter n. If the function code is set to GETPSF$, then the routine assigns scratch files in sequence beginning with file PSF$ and continuing to file PSFn$, where n is the number given as the second parameter. If the function code is set to GETPSFN$, then only one file is assigned by GETPSF$. That file is PSF$ if n is omitted or set to 0. If n is set to a value of 1 to 9, then the file PSFn$ is assigned. The function code must be enclosed by apostrophes. The only allowable function codes for GETPSF$ are GETPSF$ Assign files PSF$ to PSFn$. If n is zero or is omitted, only file PSF$ is assigned. GETPSFN$ Assign only file PSFn$. If n is zero or is omitted then file PSF$ is assigned. Note: Any other value entered for the function code parameter on the G$ETPSF procedure call causes MASM to generate an E flag on that line and print the error message. n ILLEGAL G$ETPSF FUNCTION The parameter n can be set to an integer value of 0 through 9. It may be given as an actual number, a tag that has been equated to a number or the address of a word that contains the number. The parameter n defines the highest numbered PSF file to be assigned if a group of files is requested (that is, if the function code is set to GETPSF$). Otherwise, n defines the particular PSF file to be assigned when the function code is set to GETPSFN$. If n is set to 2 and the function code is GETPSF$, then files PSF$, PSF1$, and PSF2$ are assigned. If n is set to 2 and the function code is GETPSFN$, then only one file, PSF2$, is assigned. pkt-addr Address of the packet provided by the calling program to the GETPSF$ routine. This parameter is needed only if the parameter t has been set to 'A' or 'CB'. If t is set to 'A' or 'CB', then this parameter must be included or the address of the packet must already be in register A1. If the parameter t is blank, that is, if the call is to the relocatable version of the GETPSF$ routine, then this parameter may be omitted. However, including it on the call does not cause any problems. If only the function code is given on the GETPSF$ procedure call, GETPSF uses the value in register A0 for n. If the parameter t has been set to A or CB, then the value in register A1 is used as the address of the packet required by the common bank routine. 7833 1733–004 10–3
