Purpose


GGTST	(lostr, str)

Function: Input function. Returns a character string. Use this call only if your program is written in FORTRAN IV or VS FORTRAN. Otherwise, use the function Get string (GGTSTS) instead. (See the section "GDDM-GKS restrictions" below.)

Parameters

lostr (returned by GDDM) (fullword integer)
The number of characters returned.

str (returned by GDDM) (character)
The string. In a VS FORTRAN program, the string can be of variable length. For FORTRAN IV, you must define the string as CHARACTER*80.

Operating states

WSOP, WSAC, SGOP

Related functions

Initialize string (FORTRAN only) (GINST), Request string (FORTRAN only) (GRQST), Set string mode (GSSTM)

Description

(See the section "GDDM-GKS restrictions" below.)

This function returns the string logical input value in the current event report.

GDDM-GKS restrictions

GKS does not support this function at level 2b. If this function is invoked, GDDM-GKS reports error 143.
