program or from the command line.

STRING

11 -37

CALL 60 string repeat 12 -59

CALL 61 string append 12 -60

CALL 62 number to string conversion 12 -61

CALL 63 string to number conversion 12 -62

CALL 64 find a string in a string 12 -63

CALL 65 replace a string in a string 12 -64

CALL 66 insert a string in a string 12 -65

CALL 67 delete a string from a string 12 -66

CALL 68 determine length of a string 12 -67

Use these calls when the DH485 port is configured for

DH-485 communications.

Important: CALLs 29, 49, 50, and 118 are for background operation.

Do not attempt to execute standard DH-485 calls while background calls

are enabled and active. Invalid data transfers could result.
