7.11 Character String Processing Instructions
Deletion of character string
STRDEL(P)
• This instruction deletes n2 characters data in the devices specified by (D) starting from the device (insert position) specified
by n1.
Device position where character string data to be deleted: n1=3
Number of characters to be deleted: n2=5
• This instruction stores the NULL code (00H) into the device (one word) that positions after the last device that stores the
character string data when the character string data specified by (D) is even, after the characters are deleted.
• This instruction stores the NULL code (00H) into the last device (high 8 bits) that stores the character string data when the
character string data specified by (D) is odd, after the characters are deleted.
• This instruction shifts the characters stored in the devices that position after the deleted devices by n2 characters to the
right, and then stores the NULL code (00H) into the empty device.
• QnU(D)(H)CPU, QnUDE(H)CPU: the serial number (first five digits) is "10102" or later
• Q00UJCPU, Q00UCPU, Q01UCPU, QnUDVCPU: Supported
(D): Head number (character string) of the devices where character strings to be deleted are stored
n1: Deletion start position (Setting range 1 n1 16383) (BIN 16 bits)
n2: Number of characters to be deleted (Setting range 1 n2 16384-n1) (BIN 16 bits)
