Previous Contents Index


STR$UPCASE

The Convert String to All Uppercase Characters routine converts a source string to uppercase.

Format

STR$UPCASE destination-string ,source-string


RETURNS


OpenVMS usage: cond_value
type: longword (unsigned)
access: write only
mechanism: by value


Arguments

destination-string


OpenVMS usage: char_string
type: character string
access: write only
mechanism: by descriptor

Destination string into which STR$UPCASE writes the string it has converted to uppercase. The destination-string argument is the address of a descriptor pointing to the destination string.

source-string


OpenVMS usage: char_string
type: character string
access: read only
mechanism: by descriptor

Source string that STR$UPCASE converts to uppercase. The source-string argument is the address of a descriptor pointing to the source string.

Description

STR$UPCASE converts successive characters in a source string to uppercase and writes the converted character into the destination string. The routine converts all characters in the DEC Multinational Character Set.

Condition Values Returned

SS$_NORMAL Normal successful completion.
STR$_TRU String truncation warning. The destination string could not contain all the characters.

Condition Values Signaled

STR$_FATINTERR Fatal internal error. An internal consistency check has failed. This usually indicates an internal error in the Run-Time Library and should be reported to your Digital support representative.
STR$_ILLSTRCLA Illegal string class. The class code found in the class field of a descriptor is not a string class code allowed by the OpenVMS calling standard.
STR$_INSVIRMEM Insufficient virtual memory. STR$UPCASE could not allocate heap storage for a dynamic or temporary string.

Example


30  !+ 
    !  This example uses STR$UPCASE 
    !  to convert all characters in 
    !  the source string (SRC$) to 
    !  uppercase and write the result 
    !  in the destination string (DST$). 
    !- 
 
 
    SRC$ = 'abcd' 
    PRINT "SRC$ =";SRC$ 
    CALL STR$UPCASE (DST$, SRC$) 
    PRINT "DST$ =";DST$ 
    END 
 
 
      

This BASIC program generates the following output:


SCR$ =abcd 
DST$ =ABCD
