Purpose


GURECS	(ldr, datrec, iil, irl, isl, mstr, errind, il, ia, rl, ra, sl, lstr, str)

APL code	1514
GKS RCP code	X'38006C00' (939551744)

Function: To unpack data record.

Utility function. Unpacks a data record. If your program is written in FORTRAN IV or VS FORTRAN, use the function Unpack data record (FORTRAN only) (GUREC) instead.

Parameters

ldr (specified by user) (fullword integer)
The dimension of the data record array datrec.

datrec (specified by user) (array of 80-byte character tokens)
The data record array.

iil (specified by user) (fullword integer)
The dimension of integer array.

irl (specified by user) (fullword integer)
The dimension of floating-point array.

isl (specified by user) (fullword integer)
The number of character-string entries in the string array.

mstr (specified by user) (fullword integer)
The maximum length of an entry in the string array.

errind (returned by GDDM) (fullword integer)
The error indicator.

il (returned by GDDM) (fullword integer)
The number of integer entries returned in ia.

ia (returned by GDDM) (an array of fullword integers)
The integer array.

rl (returned by GDDM) (fullword integer)
The number of floating-point entries returned in ra.

ra (returned by GDDM) (array of short floating-point numbers)
The floating-point array.

sl (returned by GDDM) (fullword integer)
The number of character-string entries returned in str.

lstr (returned by GDDM) (an array of fullword integers)
The lengths of the strings returned in str.

str (returned by GDDM) (character)
The string array.

Description

You use this function to unpack input function data records returned by Inquire *** device state and Inquire default *** device data groups of functions. It cannot be used to unpack data records returned by the Read item from GKSM (GRDITM) function.
