Indirectly programming part program lines (EXECSTRING)

Using the part program command EXECSTRING, it is possible to execute a previously
generated string variable as part program line.
Syntax
EXECSTRING is programmed in a separate part program line:
EXECSTRING (<string_variable>)
Meaning
EXECSTRING:
<string variable>:
Note
With EXECSTRING, all part program constructions that can be programmed in the program
section of a part program, with the exception of control structures (Page 474), can be extracted.
This means that PROC and DEF statements are excluded as well as the general use in INI and
DEF files.
Example
Program code
N100 DEF STRING[100] MY_BLOCK
N110 DEF STRING[10] MFCT1="M7"
...
N200 EXECSTRING(MFCT1 <<
"M4711")
...
N300 R10=1
N310 MY_BLOCK="M3"
N320 IF(R10)
N330 MY_BLOCK = MY_BLOCK <<
MFCT1
N340 ENDIF
N350 EXECSTRING(MY_BLOCK)
